The Seven Dwarves go to church and all sit down in the back pew. They're all nudging and winking at one another and whispering to Dopey, "Ask the priest, ask the priest." The priest, slightly irritated, says, "Now, please, you're interrupting the service. If you have any questions, ask me, and I will be happy to answer, and then we will return to prayer." So Dopey stands up and says, "Father, are there any midget nuns in the Church?"
The priest, mystified, says, "No, my son, there are no midget nuns. Now, let's return to our service."
After a few seconds, though, the nudging and winking and "Ask him again, ask him again" begins, and the priest is now really irritated. He stops and says, "Now, this is the last interruption I will tolerate. If you have any questions, please ask, and then please be silent." So Dopey stands up again and asked, "Father, are you sure there aren't any midget nuns in the Church?"
The priest is exasperated. He shouts, "NO! There never have been and there never will be any midget nuns in the Church! Now sit down and shut up!"
Sudden, total silence. Then six of the Seven Dwarves look at one another, nod conspiratorially, and break into a chant:
"Do-pey screwed a pen-guin! Do-pey screwed a pen-guin!"
