That's where they are from...

A woman goes to her doctor and says, "Doctor, my husband has developed a penchant¹ for anal sex. So I came to you for advice."

"Ok, let's see...does it hurt you?"

"Hmmmm .. a little."

"Do you like it?"

"Hmmm ..... well, yes."

"Then, I don't see any reason why you shouldn't do it. If you take care about not getting pregnant."

"Getting pregnant? I didn't know you could get pregnant in that way."

"Of course you can. Where do you think all lawyers come from?"
