because you always wanted to know

What an "Atomic Sit up" is:

For those of you who don’t know what an Atomic Sit-up is, it goes like this: Whoever the mark is, you get half the group to say “There’s no way [he] can do an Atomic Sit-Up.” And you get the other half to say, “Of course he can. You can do it [].” This goes on and on for a bit. This is exactly how we got Roby to drink the quart of corn syrup. When the mark finally agrees to attempt to do one, he gets down in the sit-up position. Knees bent, hands behind his head, head on the ground, lying on his back. Then a guy stands behind his head and pins his face down with a shirt. The shirt holds him down and it blindfolds him. Then you pump him up with encouragement and get him to launch his body up to do one sit-up. Of course, it’s impossible and he won’t even be able to get his head off the ground. Then everyone groans and half the group says, “See, I told you” while the other half encourages him to try again. Once he’s in position again and blindfolded, you get a guy to stand over him bare ass. You get the mark all fired up again with words of encouragement. When he launches himself upwards to do that one sit-up on the count of Three, you remove the shirt and he goes face-first hard into someone’s butt. Call it gay if you want, but it’s still hilarious.
