Lorne Michaels, executive producer of Saturday Night Live, keeps an unofficial list of people banned from hosting the show. Celebrities can get on the list for a variety of reasons ranging from uttering profanity to being an insufferable douchebag with the SNL staff.
One actor who has found himself on Lorne's list is Adrien Brody. Mr. Brody ran afoul of Lorne by dressing up like a Rastafarian while introducing the musical guest. This unplanned improvisation not only angered Lorne, but it made the show run long, the most grievous offense in the SNL rulebook.
