A young couple are making passionate love in a van when
suddenly the girl, yells out "Whip me, whip me!"

The guy doesn't have any whips on hand, but not wanting
to pass up this unique opportunity, in a flash of
inspiration, opens the window, snaps the aerial off
his van and proceeds to whip the girl until they both
collapse in sado-masochistic ecstasy.

A week later, the girl notices that the marks from the
whipping are starting to fester a little, so she goes
to a doctor.

The doctor takes one look at the wounds and asks, "Did
you get these marks having sex?"

The girl is a little embarrassed but admits that, yes,
she did.

Nodding his head the doctor says, "I thought so,
because in all my years of doctoring... you've got the
worst case of van aerial disease that I've ever seen!"
