A blonde nun and a brunette nun are walking in the town of Transylvania. All of a sudden, a little vampire bat started flying around the blonde nuns head.
She says "What should I do?" The brunette nun yells back, "Hit it...swat it down!" The blonde swats at it but can't seem to do any good.
The brunette yells, "Throw some holy water on it!" The blonde takes a small bottle of holy water from her pocket and splashes some on the vampire, but it doesn't do any good either.
The brunette yells, "Show it your cross!" So the blonde nun screams at the top of her lungs, "Get the fuck away from me you little prick!"
