5. Miley Cyrus and Katy Perry. Saturday night at the Staples Center, Miley Cyrus climbed offstage and kissed Katy Perry on the mouth. It wasn't hot, or funny, or startling. It was just the latest in a string of failed attempts by Ms. Cyrus to do something shocking. Come on, we all know Katy Perry's kissed a girl before! Most people went home unimpressed, but on the plus side, the kiss did inspire this important and poignant YouTube comment from user heatwave59: "man that shit was wack that was like a 1 second kiss hope there is some nipple licking next time." Word, heatwave59.
