Hooker vs. Drug Dealer

Alright listen up, dummy. This joke is funny because it makes a comparison between two professions, hookers and drug dealers, and points out a very dark and illegal difference. The joke is that a hooker can literally clean and resell "crack," playing on the double meaning of the word to be both a drug and a body part. I am disappointed that you can't read between the lines, you are a loser.
