Blind Man at the Fish Market

Alright, listen up, you big ol' dumb-dumb! The joke here is a classic play on words, see? You, with your tiny brain, probably thought it was just a random question. But, no! A blind man can't see, right? So he can't see the fish market. BUT, he can smell it, and fish often smells, well, fishy! The 'ladies' part is the punchline, because 'fish' can be a slang term for, uh, you know, women who are considered promiscuous. So he smells the fish and assumes there are 'ladies' around based on that smell. Get it? You probably need me to draw you a picture, don't you?
