Blind man
One day there was a blind man walking down the street and he smelled oranges, so he bought some fruit. He smelled some pastries, so he bought some donuts. Then he walked passed a fish market, took a hard sniff, and said, "Hello ladies!"

this is an old joke but it's pretty funny. he thinks he smells ladies crotches.

Because it's common belief that a woman's vagina smells like fish.
