Mercutio and Benvolio are the opposite like night and day. Benvolio is peace seeking and gentle, whereas Mercutio will fight and yell and duel until the day he dies (literally) Mercutio is mocking the reasons for quarrels towards Benvolio and it is humorous because it is the exact opposite of Benvolio's nature to do what Mercutio accuses him of. This, in a way, illustrates the close friendship between the two men.
