The Nuns and the Vampire

Two nuns are driving at night in a swamp.

A vampire flies out of a shadowy stand of moss-covered trees and lands
menacingly on the hood of their car. The nun who's driving says to the
other nun, "Quick! Sister! Show him your cross!"

The second nun leans out of the window, grabs the vampire and screams,
"GET THE #*%! OFF THE CAR!!!"
