Opening the peanut butter

From USAFA Folklore

When there is a new (virgin) jar of peanut butter at the table in Mitchell Hall, cadets break the foil seal on the top by squeezing the jar violently or by slamming a fist (or one's head) on the side of the jar until it pops. As a courtesy to those surrounding (and to attract more attention), one can yell "FIRE IN THE HOLE!" during said violent slamming of the peanut butter jar. Bonus points if peanut butter flies.

Safe to assume that this trick started after the switch from glass to plastic jars...or else the old school really did have it tougher!

In the pre-women cadet days, a "virgin" jar of peanut butter was invariably treated thusly:

After careful removal of the inner foil seal, a single cut was surgically made across approximately 3/4 of the center of the peanut butter's exposed surface. A butter knife was then inserted a couple of inches into the peanut butter at the edge of the jar close to one end of that cut. The knife was then tilted, widening the cut and exposing the subsurface in a simalcrum of female genitalia. The more "artistic" would garnish the jar by applying tea (from a tea bag) around the gash,and some would go so far as to add strawberry jam in the cut.
