The Simpsons Star Dan Castellaneta Ranked The Show's Rock Star Guests In The Most Novel Way

With "The Simpsons" having been on television for over 30 seasons, racking up such records as longest-running animated series, most People's Choice awards by a single series, most guest stars to appear on a series, and most liked television show on Facebook (via Guinness World Records) it's an honor for anyone to appear as a guest star. In fact, even in the cases of such music legends as Paul McCartney, The Who, and U2, it's hard to tell who should be more honored by the appearance: the show or the stars.

With all the rock stars that have appeared over the years, there's no shortage of fun stories about them. McCartney, for example, insisted that he would appear in the Season 7 episode "Lisa the Vegetarian" if the show's creators promised that Lisa would remain vegetarian for the rest of the series. The producers have kept their word to this day. Then there's the story about the time Bono mooned the show's music director over a comment about the U2 frontman being too pitchy. Of course, there's also the story of the Season 7 episode "Homerpalooza," which featured the Smashing Pumpkins, Sonic Youth, Cypress Hill, and Peter Frampton. The episode almost featured another '90s rock mainstay in Hole, but Sonic Youth threatened to pull out of the episode if Hole's controversial frontwoman, Courtney Love, was involved.

So which bands are too cool to show up on time for their recording sessions? Dan Castellaneta, who voices Homer Simpson, amongst others, explained once on "Late Night with Conan O'Brien" that some rock stars are too cool for the proverbial school.
