 Carla is the bar s resident sports trivia buff, and takes on all comers. Woody thinks he s up to the challenge and tries to memorize all in Carla s sports book. He ultimately goes just a little too far in his studying. Diane is doing some studying of her own. She is taking a psychology course on human sexuality, and is racking her brain to come up with an interesting term paper topic. Sam figures that sex is his area of expertise, and thus offers to be Diane s term paper subject. She s a bit reluctant at first due to their past sexual history, but Sam is so adamant, she agrees. Without Sam s knowledge, she writes a paper on Don Juanism. The paper gets raves from her professor, who thinks it s publishable. His only reservations are that "Trevor" - the name she s given Sam in her paper - is too perfect an example of the subject that he could be construed as being made up. Sam quickly dispels that by revealing himself to the professor, Sam still thinking that the paper is solely about his great sexual prowess. The professor s second reservation is that the paper contains no effect of Trevor s actions, and thus requires at least the account of one female who has fallen under the manipulative spell of Trevor; obviously Diane has a first hand account of that. Diane does the rewrites, with which the professor is happy. Still thinking that it s a paper on his sexual prowess, Sam invites Diane s class to the bar for a first hand account of his life. Halfway through displaying his true Don Juanism to the class does Diane finally explain to Sam, in private, the true nature of her paper. Sam is heartbroken. But Diane tries to assure Sam that the paper is a theoretical one designed solely to get a good grade, and that in reality Sam is a wonderful human being who can carry on a non-sexual relationship with woman. Sam and Diane test that theory with moderate success. Meanwhile, Cliff is growing more, in his mind, specialty vegetables. Instead of a potato look-a-like of Richard Nixon, he s now got a squash with what he deems has a map of the Hawaiian Islands on it.
