It's just like in the movie City Slickers. (If you haven't seen it, you should. Billy Crystal is awesome in it.) The three main characters are really into sports, especially baseball. It's a recurring topic of conversation throughout the movie. While a group of people are talking, baseball comes up. The woman in the group says she doesn't understand men and baseball - after being asked if she doesn't like baseball, she replies:
"No, I like baseball. I just never understood how you guys can spend so much time discussing it. I mean, I've been to games, but I don't memorize who played third base for Pittsburgh in 1960."
As soon as she finishes her sentence, the three guys all say, "Don Hoak," proving her point that men memorize everything about a sport they like.
