Ok, a friend of mine was telling me about this teacher of his that is just a complete ditz. Keep in mind, she has doctorate. Well one day, she was trying to use a projector to play a move off of her computer. Well she would keep playing it, but no sound would play. Everyone started screaming at her that she needed to turn the volume up. So she started turning the volume dial on the projector. Growing impatient, people began tell her to use the yellow speaker thats on the computer. So what does she do? She walks up to the projector screen, and starts poking the speaker with her finger! Everyone just went into a riot and that teacher had no idea why.
