When Captain Kirk fights, he wants the whole world to know. With hurt feelings over a missing invitation to George "Sulu" Takei's wedding, William Shatner aired his pain in multiple Youtube videos.

For mysterious reasons we still don't understand, Lindsay Lohan took an imaginary feud with Scarlett Johansson to an interesting medium - a bathroom wall. In 2006, Lohan scrawled a particularly indecent version of "Scarlett Johannson is a %$&^" on a Manhattan stall.

We watched Disney cutie Selena Gomez's harmless Youtube video with Demi Lovato, talking about t-shirts and teeth - then we watched Miley and Mandy's needlessly cruel parody of her fellow Mouseketeer and couldn't figure it out. Turns out, neither could Selena - she told MTV News, "There's no feud - there's nothing to feud about, so why start a fight?" Class act, that one.
