U2 will help the Simpson clan celebrate the 200th episode of "The Simpsons" this weekend, and a sneak peak at the episode shows that Homer actually joins the band on stage.

In the episode (which airs this Sunday at 8 p.m. on Fox), Homer interrupts U2's PopMart spectacle (first popping up on the band's giant video screens, and then joining the band on stage) to campaign for votes in his run for Springfield sanitation commissioner.

The band had other reasons for appearing on the show though. "Well, people like you have reduced us to cartoons before we ever got involved in 'The Simpsons,'" U2 frontman Bono told MTV News. [article id="1451415"]"I'm here to kiss Homer Simpson's bottom." [600k QuickTime][/article]
