Yes, there is a pun in Act 3 of Romeo and Juliet when Mercutio says, "Ask for me tomorrow, and you shall find me a grave man." This is a pun because "grave" can mean both serious and also a burial place.
The first thirty lines of the play are all puns. The first set are on the words "collier" (a person who carries coals), "choler" (anger) and "collar". Then there is a pun on "move"--Sampson says he is moved to anger, meaning his emotions are engaged, and Gregory takes "moved" in the literal sense, suggesting that Sampson will "move" where a brave man would stand. Then he says he will push the Montagues to the wall, and they get into a punning session about the men having their backs to the wall and getting the women up against the wall. Then we have these lines:
Sampson: I will be cruel with the maids--I will cut off their heads.
Gregory: The heads of the maids?
Sampson: Ay the heads of the maids, or their maidenheads. Take it in what sense thou wilt.
But they don't stop there. Gregory says, if they take it in sense, they must feel it. (sense=feel) And Sampson replies that they (the maids) shall feel it "while I am able to stand". In this context, he calls himself a "pretty piece of flesh" and Gregory responds (bearing in mind that "fish" was not "flesh" for the purpose of the Catholic Friday fast) that that's good because if he was a fish he'd be a shrivelled dried up fish (a Poor John). The double meaning of all this isn't hard--er, difficult to see.
Romeo says that the flies are better off than he is because they can land on Juliet and he is not even allowed to see her. "Flies may do this but I from this must fly" he says. The pun is of course on the word fly.
