Why the hell did you do that?

Have you ever wanted to ask someone why they did something stupid? I feel like most of the time that question goes unanswered purely for the sake of being tactful. I say fuck that. Here are some questions I would like to ask people for honest answers to:

William H. Macy - you are a great actor, why the fuck did you agree to be in Wild Hogs?
Samuel L. Jackson - Were you fucking high when you agreed to be in "The Man"?
George Lucas - JarJar Binks? C'mon. Who has pictures of you blowing a goat that could blackmail you into that decision?
John Kerry: I know that you're kind of a tool, but why did you have to be such a pussy and back down from those SwiftBoat guys? Shit, why did you even go with the Vietnam war hero bit in the first place?
Zach DeLaRocha: Was Rage not popular enough for you? Why'd you break the band up?

That's just a few that were brewing in my head today.

Gimme some of yours please.
