Lipstick Answers

A man goes to his doctor & says, “Doctor, Doctor, please help me! I’ve got a problem.”
The doctor examines the man & sees that the man has a red ring around his penis. The doctor gives him an ointment & asks him to go home & rub on the problem area.
Just moments after he applied the ointment the things gets cleared up this guy is really impressed how fast it worked & wonders this must be super wonder medicine, so he calls up the doctor & says “It’s all cleared up!, But what was that medication you gave me?”
Doctor: “Lipstick remover.”
