DAVE: Who us? Says who? Would you like to step outside and accuse me of likin' to brawl? I don't know that guys like to fight so much as I think society expects us to fight. Too often, men act a certain way because they think that's how they are supposed to behave. Girls do this too—it just doesn't end with bloody noses.
BILL: Fighting is a guy's way of saying, "Hey, I really like you, man," without having to use actual words. Not really. And let me point out that not all guys like to fight. In fact, most guys don't like to fight. My experience is that less intellectually developed of a species tend to resort to physical means to solve their differences. Translation: The majority of guys who fight do so because they're idiots.
