This is one of the best jokes ever. :P
Two nuns were traveling through Europe in their car, and ended up in Transylvania somehow. As they are stopped at a traffic light, out of nowhere a vampire jumps onto the hood of the car and hisses at them through the windshield.
“Quick, quick!” shouts the first nun, “What should we do?”
“Turn the windshield-wipers on”, the second non cries, “that should get rid of him!” But he hangs on and continues hissing at the nuns.
“What shall I do now?” she shouts.
“Try the windshield washer, I filled it with holy water before we left the Vatican,” replies the second nun.
But the persistent little bugger still hangs on to the car.
“Now what?” shouts the first nun in despair.
“Show him your cross!” says the second nun.
So the first nun leans out of the car-window, shaking her first, screaming
“Get the fuck off our car!”
