power situp
This is when you get some beefcake who thinks hes hot shit to show off. Tell him that you are going to put a towel over his head and see if he can do the situp while you pull down. Being the arrogant moron that he is, he gladly tries. Have someone pull their pants down over his head and release the towel. The unsuspecting douchebag's nose goes right up the guys ass.

atomic situp
person 1 is baited into performing "the hardest situp ever". Person 1 then lies on the floor on their back and told cross hands on chest. Person 2 then holds a towel over the face of person 1 covering the eyes telling him sit up quickly with all his strength when he say to. Meanwhile person 3 has removed their pants and is squating over person 1's face with out him knowing. Person 2 then tells person 1 to sit up quickly and removes the towel as soon as the sit up begins. The result is person 1's nose is planted into person 2's ass.
