Sharon has never told anyone her most secret fear. She thinks that she is part werewolf because that is the only possible explanation for all her strange feelings and behaviors. For example, sometimes she has terrible sexual desires that she can just barely restrain and other times she has no sexual desires at all.

Sometimes she has enormous emotional changes, feeling love, hate, happiness and sadness, all within a few minutes. Finally, she must always carry a winter coat because even on the hottest days she has cold flashes. There is only one brain area that is involved in all of these various functions. Which part of Sharon’s brain is somehow malfunctioning and causing all her symptoms?
For the last six months, ever since Sam was accidentally hit on the side of the head by a baseball, he has rented the same video: Batman.

There is a tiny bug that lives under beds and comes out at night when a person is sound asleep. The bug crawls into the person’s ear and keeps on going until it reaches the brain. Very quietly so as not to wake the person, the bug begins to eat away its favorite part of the person’s brain. The next morning, as the person gets up, he walks to the bathroom in a very clumsy way.

Each time Dave talked, people laughed and said that he had one of the best comedy routines that they had ever heard. Dave would begin with what seemed like a normal sentence but after a few words he would start talking about an entirely different topic, and after a few more words he would go off on another area.
