A young couple were making passionate love in the back of the guy's van (you know, shag carpets, big double mattress in the back... all that) when suddenly the girl, being a bit on the kinky side, yells out "Whip me! Big Boy, Whip me!!!" The guy not wanting to pass up this unique opportunity, obviously did not have any whips to hand, snaps the radio antenna off his van and proceeds to whip the girl until they both collapse in sadomasochistic ecstasy.

About a week later, the girl notices that the marks left by the whipping session are starting to become infected a bit so she goes to the doctor. The doctor takes one look at the wounds and asks, "Did you get these marks having sadomasochistic sex in a van?" The girl a little embarrassed but admits that, yes, she did.

Nodding his head knowingly the doctor exclaims, "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."
