Now, tell him you have a headache

It's a beautiful warm spring day and a man and his wife are at the
zoo. She's wearing a cute, loose-fitting, pink spring dress,
sleeveless without straps. As they walk through the ape exhibit and pass in
front of a very large gorilla, the gorilla goes ape. He jumps up on
the bars, holding on with one hand (and 2 feet), grunting and pounding
his chest w/the free hand. He is obviously excited at the pretty lady
in the sheer dress.

The husband, noticing the excitement, suggests that his wife tease the
poor fellow. He tells her to pucker her lips, wiggle her bottom, and
flirt with the ape.

She does and the gorilla gets even more excited, making noises that
would wake the dead. Then the husband suggests that she let one of her
straps fall; she does, and the gorilla is so excited, he's just about
to tear the bars down.

The husband then suggests that the wife lift her dress up above the
thighs... this drives the gorilla absolutely crazy.

Then, quickly the husband grabs his wife by the hair, rips open the
door to the cage, slings her in with the gorilla and says, "Now, tell him
you have a headache."
