well butt fuck borats fake but the shit he does isnt, only the pam anderson thing was stages (like two others may have been slightly staged like the dinner).
I found jackass FAR better. Like I was seriously busting a gut laughing. When I was laughing at Borat it was more like one of thoses half assed forced laughs where your face starts to hurt because you are really only laughing because you feel you have to...
Jackass is funny, but stupid. There can't be much thought to thinking up wearing a mask and having someone fart into it. Borat wins hands down in my opinion.
