Two nuns, Sister Marilyn and Sister Helen, were travelling through Europe in their car. They got to Transylvania and were stopped at a traffic light when, suddenly, out of nowhere, a midget Dracula jumped onto the hood of the car and hissed through the windshield.
"Quick, quick!" shouted Sister Marilyn. "What shall we do?"
"Turn on the windshield wipers. That will get rid of this vampire," said Sister Helen.

Sister Marilyn switched them on, knocking Dracula about, but he clung on and continued hissing at the nuns.
"What shall I do now?" she shouted.
"Switch on the windshield washer.  I filled it up with Holy Water in the Vatican," replied Sister Helen.
So, Sister Marilyn turned on the windshield washer. The vampire screamed as the water burned his skin, but he clung on and continued hissing at the nuns.
"Now what?" shouted Sister Marilyn.
"Show him your cross," said Sister Helen.
Sister Marilyn opened the window and shouted, "That's it...get the fuck off our car!"
