ultimate sit-up

To tell one of your friends to try and do the hardest sit up. Place a towel over there eyes and hold it tight to the ground. While there struggling to get up have another person pull down there pants exposing there ass. The ass will be over the person doing the sit-up's face. Pull the towel away and the sit-up persons face should shoot up straight into the buthole of the person.

Ranger Sit-Ups

n. Named for the U.S. Army Rangers, an elite group of soldiers.
Commonly done as a military initiation joke, the subject is blindfolded, and two people hold his shoulders down. Another soldier (more commonly one who has been in the service for a while) stands with his pants down so that when the other two release the subject, his face plants right in the standing soldier's ass-crack.

"Man, my buddies thought it would be cool to have me do Ranger Sit-ups. Even the sarge was in on it..."

"Alright, private. Time to try your luck at Ranger Sit-ups."
