5. Justin Bieber - The pop star was in the middle of a concert Saturday night when he suddenly bent over, turned his back to the audience and spewed out an inadvertently accurate metaphor for his music onto the stage. Extra security staff was immediately brought in to prevent the first seven rows from charging the puddle with squeegees and Tupperware containers. Bieber claims the vomiting was brought on by drinking too much milk — an excuse that's as unlikely as it is adorable. Unfortunately, he was able to recover and finish the show.
