Just because a band is fictional doesn't mean it can't be as popular as its real world counterparts. (Admit it, you still have that Zack Attack album buried in your closet somewhere.) Whether spoofing a famous act, or creating their own inept sound, these fake bands often wear their love of the music world on their sleeves. Documentary Now!'s chronicling of the soft rock giants Blue Jean Committee is just the latest example.

It’s no surprise that the folks behind the show (Fred Armisen in particular) have a long track record of finding the funny in the music industry. (It takes musical talent, along with some serious comedy chops, to pull off the smooth lyrics of "Catalina Breeze.") So, while Blue Jean Committee, or A Mighty Wind’s The Folksmen, could easily have been on this list, it's not a shock that the folks behind them are. If you love music and comedy in equal measure, you're going back to that well more than once. Here are some of the funniest fake bands to ever turn it up to eleven.

15. Citizen Dick, Singles

https://youtu.be/TbZZYMooLnQ

Citizen Dick, the band from Cameron Crowe's alt rom-com Singles, was both a spoof of, and a turning point for, the Seattle grunge scene of the early '90s. While many of the bands from that scene were cult hits, the Singles soundtrack helped turn them into superstars. It's no surprise that the made-up band, fronted by Matt Dillion's Cliff Poncier, could hold its own with so many grunge standouts, considering 3/4ths of its members were in a little group called Pearl Jam. Heck, Dillion even wore Pearl Jam's bassist Jeff Ament's clothes for most of the shoot. Now that's commitment.

14. Titannica, Mr. Show with Bob and David

https://youtu.be/wmNApZRy3wk

With hits like "Try Suicide" and "Try Again," no one rocked harder than Titannica, the heavy metal band made famous in one of the downright weirdest sketches from the cult hit Mr. Show. But no matter how messed up their music was, the boys of Titannica knew it couldn't hold a candle to the creep show that was their biggest fan, a chipper kid with the body of a wet cigar. This sketch is a surreal lesson in the power of music.

13. Sonic Death Monkey/Kathleen Turner Overdrive/Barry Jive and the Uptown Five, High Fidelity

https://youtu.be/1V_-iZYIofU

You can watch Jack Black become a star in the final minutes of the 2000 cult hit High Fidelity, as his character Barry takes the stage to front his frequently renamed band. While Barry may not be able to decide on a sound for his band, Jack Black knows how to deliver when given the chance. A fun movie about and for music lovers, this scene is the cherry on top. It doesn't matter what type of music you're playing, as long as you leave it all on the stage.

12. Dethklok, Metalocalypse

https://youtu.be/mSLqhZk-hA4

When Metalocalypse co-creator Brendon Small was working on his previous Adult Swim hit, Home Movies, few would've guessed that he'd be responsible for one of the most face-meltingly metal bands to ever grace the small screen. And Small didn't just dream up Dethklok -- he writes and performs every one of their songs with co-creator Tommy Blacha. While Dethklok has surpassed mere superstardom on their show, becoming the seventh largest economy in the world, their popularity in the real world isn't far behind. Small and Blacha have fronted more than one tour as the band, and recently played the comedy/music festival Festival Supreme, created by none other than Barry Jive himself, Jack Black.

11. David Brent and Foregone Conclusion, BBC's The Office

https://youtu.be/QlSv818d1Rk

In The Office Christmas Special, which served as the final episodes of the beloved BBC series, co-creator Ricky Gervais revealed his character David Brent had finally chased his dreams of stardom too far, by recording a cover version of the hit "If You Don't Know Me By Now." But while the show was wrapping up, this sojourn into music was just the beginning for the former general manager of the Slough branch of Wernham Hogg. Gervais has kept up with his most famous character, recording a song for Comic Relief and creating a series of YouTube guitar tutorials. This all culminated in a tour with the made up band Foregone Conclusion. Rumor has it, he's even been prepping a movie to cover Brent's presumably delusional journey through the English music scene. While knowing when to say goodbye is a gift, it's not something David Brent would be capable of, so why should we expect any different from his creator?

10. Dr. Fünke’s 100% Natural Good-Time Family Band Solution, Arrested Development

https://youtu.be/3capE91-270

Playing in Dr. Fünke's 100% Natural Good-Time Family-Band Solution was a great excuse for some family bonding time, while promoting a worthwhile product to boot. At least that's what David Cross' Tobais Fünke thought on the first season of Arrested Development, forcing his family to play in the pharmaceutical funded family band. More a promotional vehicle than a hit maker, any chance to see the dysfunctional Fünke family interact is worth inclusion on this list. The music may not be worthwhile, but the fury behind Maeby's eyes is.

9. The Rutles, All You Need Is Cash

https://youtu.be/fJqp_KvOHts

The Beatles were no stranger to parody, as you'll see later in this list. But what separated The Rutles from the legion of spoof bands that plagued the world as the '60s turned to the '70s was the guidance of Monty Python Hall of Famer Eric Idle, and a will to not just send up, but really satirize the boys from Liverpool. The band first premiered in 1975 on Rutland Weekend Television, a sketch show fronted by Idle, and immediately took on a cult following. George Harrison was such a fan, he ended up appearing in The Rutles' feature film All You Need Is Cash.

8. Ian Rubbish and the Bizzaros, Saturday Night Live

http://www.hulu.com/watch/478685

Long before Fred Armisen made his name on Saturday Night Live, he was a drummer for underground punk bands. The Clash in particular was an inspiration, and even with a right turn into comedy Armisen's love of punk never diminished. That's evident in this SNL sketch about a very Sid Vicious-like rock star who hates everything...except for Margaret Thatcher. Initially just a one time performance, the bit struck such a chord that Armisen reunited The Bizzaros for his last sketch as an SNL cast member. Still not done with his alter ego, he's since taken the band into the real world, playing gigs as the foul mouthed punk rocker with a love for the Iron Lady.

7. Wyld Stallyns, Bill and Ted’s Excellent Adventure

https://youtu.be/yY4UrdZOfJY

If your band is responsible for world peace, you probably deserve a spot on this list. While Bill and Ted start off as musically inept, one visit to the utopian future brought about by their sweet jams reveals them to be more than a mere rock band. They're modern day messiahs, which is most excellent.

6. Dr. Teeth and the Electric Mayhem, The Muppet Show

https://youtu.be/hAPxsaRB30M

For many of us, Dr. Teeth and the Electric Mayhem was the first exposure we ever had to a rock band, real or otherwise. For the better part of four decades the Electric Mayhem has kept at it, managing to cover everything from classical to "Crocodile Rock" with a drummer so wild he has to literally be chained to the set. Even Keith Moon wasn't kept in shackles.

5. Faith +1, South Park

https://youtu.be/NrhJT98IoaQ

It's tough to pick between the two most famous bands to ever be fronted by foul mouthed fourth grader Eric Cartman. While the boyband Fingerbang is for sure a classic, Cartman's Christian rock band Faith +1 combines his megalomania, cynicism and racism into a beautiful collage of sacrilegious majesty. And considering South Park is far from done, who knows what other bands creators Trey Parker and Matt Stone have up their sleeves.

4. PoP!, Music & Lyrics

https://youtu.be/xVkU8dDSC9w

Hugh Grant is perfectly cast as one half of a Wham!-esque group in this charming rom-com. And he learned from the best -- Martin Fry from the new wave group ABC served as Hugh's vocal coach.

3. Sexual Chocolate, Coming to America

https://youtu.be/KzANAr1V82c?t=10s

Both "good and terrible," Randy Watson may not have been the legend he believed himself to be, but to fans of Coming to America, he and his perfectly named backup band were responsible for one of the funniest scenes in this classic comedy. Eddie Murphy was at his peak here, donning the puffy faced prosthetics necessary to truly inhabit the pitchy son of Jackson Heights. And having Morris Day of The Time fame on guitar didn't hurt either.

2. The Blues Brothers, Saturday Night Live, The Blues Brothers

https://youtu.be/rRvuSy6-PuQ

As the '70s gave way to the '80s, The Blues Brothers, along with their creators John Belushi and Dan Aykroyd, were forces of nature. The two comedians and friends first premiered their creation on Saturday Night Live, promptly launching a sensation. At one point, Belushi found himself the star of the week's number one film (Animal House), number one television show (Saturday Night Live), and singing on the number one album (Briefcase Full Of Blues). Belushi and Aykroyd would soon add a hit Blue Brothers movie to that hot streak. Combining their perfect chemistry with a whole lot of soul, Jake and Elwood transcended comedy, and helped relaunch the popularity of the blues genre itself.

1. Spinal Tap, This Is Spinal Tap

https://youtu.be/4xgx4k83zzc

If the last two entries show you anything, it’s that the '80s were the high water mark of fake bands in popular culture. And yet, with all the classics that came out in that decade, there was never any doubt who would sit at the top of this list. Spinal Tap isn't just a movie. They aren't just a band. They're the id of rock music, manifested into reality by the all-star team of Rob Reiner, Christopher Guest, Michael McKean and Harry Shearer. In the ridiculous world of rock and roll, which already operates in a perpetual cycle of self parody, finding the balance of comedy and reality is no easy task. By using the form of a documentary, director Rob Reiner allowed his brilliant cast to improvise their way through the movie, creating the gold standard of fictional bands in the process. The film also introduced the "mockumentary" form to a mainstream audiences, which has gone on to become one of the most popular styles of comedy over the last three decades.
