Winnie Mandela goes to the Doctors, Doctor says to her to strip and kneel in the corner facing the wall ... he then tells her to go to other corner of the room and do the same.
After looking for a while, he then tells her to get dressed.
"So, doctor, what is the problem?"
"I have no idea, I've not checked you yet, I'm getting a new black leather couch delivered and I was wondering where to put it."

I'm stealing that.
