12. Seth MacFarlane (2013)
So sweet: The Make-a-Wish Foundation decided to grant the request of some precocious child ravaged by terminal doucheness by letting him take over Hollywood's biggest night. Oh no, wait – that's Seth MacFarlane! He opened with a month of skits about what a big deal he is, unwise considering he wasn't one of the hundred (or two hundred) most famous people in the room. He sang. He danced. He told jokes about how he can't tell black guys apart. At the end, when Argo won Best Picture, they cut away before producer George Clooney could say "thank you" because Seth needed time to sing one more show tune. What a tool.
