The three dwarves were in rome and went to the nearest nunnery. They got to talk to the mother superior.

"Excuse us, but can you tell us where the dwarf nuns are?"

"Sorry", she replies, "but there are no dwarf nuns here."

"Well, are there any in the city?"

"No, there are no dwarf nuns."

"What, none anywhere in Europe?"

"No, little man."

"None in the entire world."

"Take my word for it."

At this, 6 of the seven dwarves burst out laughing.

The Mother Superior asks, "What's so funny?"

"Dopey just kissed a penguin."
