leprechauns, midgets and nuns

Two leprechauns went to the convent and begged an audience with Mother Superior.
"Well, how can I help you little people?" asked Mother Superior.
The larger and more intelligent looking of the leprechauns asked: "Oh Mother Superior, would you be knowing of any midget nuns here at the convent?"
"No," says Mother Superior, "I don't have any midget nuns here at the convent".
"All right then, Mother Superior, would you be knowing of any midget nuns in all of Ireland then?"
"No, no," replied Mother Superior, "I don't know of any nuns who are also midgets in all of Ireland at all."
"Well then Mother Superior, in all of nundom, in the whole world of all the nuns, would you be knowing, then, of any midget nuns?'
"No, I would not, there are no midget nuns in the whole of the world!" replied Mother Superior, "and would you please tell me what this is all about!!?"
The asking leprechaun turned to the stupid leprechaun and said: "See, it's as I told you all along, you've been fucking a penguin."
