In the rules for life, the first one is always this: Don't Get Caught. Other rules may vary by location and other factors, but especially in college when numerous activities of questionable legality are occurring rule number one is don't get caught.
Rule number two is frequently Don't Die, unless not dying would interfere with rule number one.

or, on the outside end of a phone call from jail:
Jason: You broke rule number one!
