'I'll Tumble 4 Ya' has to be one of the most ridiculous hit singles that any international superstars have given the world.

The first season of 'Community' stumbled a bit because the plotlines too often veered into realism, but that is not a problem anymore. Not when prize episodes concern a campuswide blanket fort, or a secret garden with a magic trampoline.

When Ke$ha tries to rap like L'Trimm, she sounds like any ordinary lonely teenage girl stuck in a nowhere town, singing along to her radio and dreaming of a party where she's the star. Ke$ha's greatness is that in her voice, you can hear both the loser girl and the star. All hail the Queen of Noi$e!
