Iconic pop star Ke$ha made an appearance on 'The Simpsons' (Sun., 8PM ET on Fox). She sort of appeared, at least. While Ke$ha herself didn't guest star on the show, her hit song 'Tik Tok' was a big part of the comedy.

During the show's opening "couch gag," a bunch of the show's most famous characters lip-synch along to the song. It's a funny move for the show, but also an odd one. Watching Lisa Simpson sing the lyrics "Wake up in the morning feeling like P. Diddy" is a little weird. But still, it's pretty hilarious. Do you think that Ke$ha and 'The Simpsons' are a good match?
