"The Two Eskimos" joke

Two eskimos, a big one and a little one, go to their local Alaskan convent
with a question. The big one nudges the little one and says, "Go ahead,
knock on the door, knock on the door."
The Mother Superior answers the door. Again, the big eskimo nudges the
little one and says, "Go ahead, ask her the question, ask her the
question."
The little eskimo timidly says, "May we speak with the midget nun that
lives here please?"
The Mother Superior answers, "There are no midget nuns living here."
The big eskimo starts nudging the little one again and says, "Go ahead, ask
her the other question, ask her the other question."
The little eskimo asks in a quavering voice, "Well, are there any midget
nuns in Alaska?"
The Mother Superior responds uncertainly, "Why no, I don't believe so."
With this the big eskimo falls down and rolls on the ground, clutching his
belly as he laughs uncontrollably. "See", he says to the little eskimo, "I
told you you screwed a penguin!"
