1) When the professor asks a question, raise your hand. If the professor calls on you, point to someone in the suivant row and say "He knows." Pick a different person each time.
2) Buy a watermelon. Give it to the professor. If he/she asks, say "They were out of apples."
3) Bring a fishing rod. Try to catch things on the professor's desk.
4) Bring a tape player and a tape of a thunderstorm. Keep it hidden. Sometime during the lecture, start the tape, stand up, claim that the professor has angered the gods and leave. Watch to see how many students follow toi after the tape starts playing.
5) Make reserved seating cards and place them on the desks before class.
6) Bring a flash camera. Take pictures every few minutes, using a very bright flash. If anyone complains, say that toi didn't see any sign saying toi couldn't bring cameras.
