A woman goes to the doctors, and says, "Doctor, I've got a bit of a problem. I'll have to take my clothes off to show you."

The doctor tells her to go behind the screen and disrobe. She gets undressed, and the doctor goes around to see her when she is ready.

"Well, what is it?" he asks.

"It's a bit embarrassing," she replies, "These two green circles have appeared on the inside of my thighs¹."

The doctor examines her and finally admits he has no idea what the cause is. Then he suddenly asks, "Have you been having an affair with a gypsy lately?"

The woman blushes² and says, "Well,... yes, actually I have."

"That's the problem!" the doctor says, "Tell him that his earrings³ aren't made of real gold!"
