I also don't understand why people think Russell Brand is funny. He irritates the crap out of me. Katy Perry is also annoying but at least she is just shamelessly poppy and bubblegummy, whereas Brand's whole thing just seems to be "I'm a man wearing eyeliner, I'm so rock n roll, whoa," - at least from the 15mins of his standup I saw that was my impression. Dude, you're just focussing on your (not even interesting) appearance because you actually aren't very funny.
Katy Perry also has very nice breasts.
