An elderly black man goes to see his doctor for help with his sexual performance issues.
The doctor explains that the sex enhancing pills aren’t going to work this time.
The man goes back to the doctor a month later for a follow-up.
This time he is wearing a new tuxedo, shined shoes, and a top-hat.
The doctor is impressed and asks what the occasion is.
The old man says, “If I’m gonna be impotent I’m gonna look impotent!”
