I lived in Stanford. First week Freshman year several of us grabbed the hall president (a fairly obnoxious senior)out and threw him into St. Joseph's Lake. Turns out he couldn't swim (he was in ROTC so he got to skip the swimming test) and one of our group had to jump in to save him.

Bob Burger (starting OG) lived in Stanford as well. One night a small group (3 or 4) of us pennied him into his room. When he figured out what was going on he started pounding on the door to knock the pennies out. We all ran like hell. Got around the corner just before he opened the door.
