Two nuns, Sister Carol and Sister Helen, are traveling through Transylvania in a car. Suddenly, a vampire jumps onto the bonnet of the car and hisses at them through the windscreen.
"Quick, quick!!" shouts Sister Carol. "What shall I do?"
"Turn the windshield wipers on; that will get rid of the abomination," says Sister Helen.
Sister Carol switches them on, which knocks the vampire about, but he clings on and hisses again at the nuns.
"What shall I do now?" she shouts.
"Switch on the windshield washer. I filled it up with Holy Water in the Vatican," says Sister Helen.
The vampire steams as the water burns his skin, but he clings on and hisses again.
"Now what?" shouts Sister Carol.
"Show him your cross," says Sister Helen.

Sister Carol opens the window and shouts: "GET THE F*** OFF MY CAR!!"
