An older couple were scrutinizing a piece of cubist art and listening to an audio tape that described the piece.
"It says there is genitalia in that painting, but I can't find it!" complained the woman to her husband. "I have looked and looked! And I can't find it!"
"Well, that's ok. I'll help you," said the husband. They marched off to carefully search the painting for the missing vagina.
I hope they were both satisfied.
