I'm gonna be a stick in the mud and just say that I hate all pranks of all varieties, all the time. Prank calls suck, hidden camera jokes suck... they all suck, with no exceptions under any circumstances, including when they're done to people I don't like. They're a mean-spirited way to take someone's faith (or at least hope) in the inherent goodness of humanity and yank it out from under them.
That is all.
(Edit: and I'm not saying this because I think Palin's awesome. She's a doofus, and I feel bad for her that she's been pulled into a limelight that she clearly can't handle.)
I agree with this, I just muted the video and read the comments to gauge the reaction. Prank shows make me cringe, because I just sympathize too much.
