One Sunday a guy gets grim news from his doctor, he has only a few hours to live. He decides to get laid one last time before he dies, like all sensible people. Being single, his only option is a hooker. However, being Sunday the bank is closed, so he has to make due with what's in his wallet, $5. He finally finds a girl willing to screw for $5. He starts going and suddenly stops. "Something just doesn't feel right about this" he says to his hooker. The hooker rushes out of the room and comes back in a few minutes later. She convinces him to try again, so he does. "Wow...this is sooooo much better, this might be the best sex I've ever had. What did you do differently?"

"Oh, I just picked the scabs and let the puss run"
