Jesse Walsh: Hey, Grady, do you remember your dreams?
Ron Grady: Only the wet ones.
Trivia: Take a close look at the bus driver at the beginning of the movie. It is Robert Englund without his Freddie makeup/costume.
Answer: I think the coach's death was a play on his character being at a S&M bar. People who frequent those places are usually into bondage and being dominated. Hence being tied up, and whipped with the towel. It also fits in with the homoerotic subtext throughout the movie.
