Elaine Miller: Keep the small bills on the outside and call me if anyone gets drunk.
William Miller: I will call you if anyone anywhere gets drunk.

Trivia: When Penny Lane asks William to go with her to "wherever", she asks him twice. The first time William didn't like the way he said it, so he asked her to ask him again while the cameras were still rolling. Cameron Crowe like it so much that he kept the entire sequence in the film.
