Gotcha, Seacrest: Ryan Seacrest is a favorite target of Joel McHale's, so naturally the Soup snarker went after the American Idol host, "hacking" his Twitter account and his website with doctored photos of Joel-as-Ryan.

I do what stars do," the 16-year-old sensation says in clip titled "Bieber Takes Over." "I ride on yachts. I autograph lady lumps. And I pay people to slap them."
