The Situation
Zakk Wylde (seems like a douche)
Ozzy Osbourne (I actually imagine him to be pretty nice guy to his fans, but.... him perpetually mumbling incoherently while I awkwardly pretend I understand what he's saying doesn't sound like a good time).
Seth MacFarlane
Troy Aikman ( I was a die hard 9er fan in the 90s)
Vince Vaughn (he just grates me in pretty much every movie role, he'd probably grate me irl too)
