This what you do walk in with a trench coat
Act really shady that day
and than in the middle of passing period
Run down it and act like your gonna pull a gun out
Than stop and say "ive been shot!"
Than a pull out a twinkie and say"With a craving for a delicious Twinkie"
and eat that mofo, no one will see it coming
While in a crowded class room, when its pretty calm and quiet. Stand up slowly and raise your hands up and yell, " I am erect!!" I did it in my drivers ed class.
