The 7 Dwarves are standing outside a convent. Then Happy goes and knocks on the door. A nun answers and says "Can I help you, my child?" Happy says "Are there any 3 foot nuns in this convent?" The nun is puzzled, and says "No, there are no 3 foot nuns in this convent." Happy thinks for a minute, then says "Are there any 3 foot nuns in this city?" The nun says "No, there are no 3 foot nuns in this city." So Happy leaves and forms a huddle with the rest of the dwarves. Then a few minutes later, Doc leaves the huddle and goes and knocks on the door. The same nun answers and says "What now?" Doc says, "Ok, are there any 3 foot nuns in this state?" The nun says "No! There are no 3 foot nuns!" Doc thinks, then says "Are there any 3 foot nuns in this country?" The nun is starting to get mad, and says "NO! THERE ARE NO 3 FOOT NUNS!" So Doc leaves and returns to the huddle. A few minutes later, Sleepy goes and knocks on the door. The same nun answers. Sleepy says "Are there any 3 foot nuns on this continent?" The nun says "NO!! HOW MANY TIMES DO I HAVE TO TELL YOU??? THERE ARE NO 3 FOOT NUNS!!" Sleepy says "Are there any 3 foot nuns anywhere in the world?" The nun says "NO!!" and slams the door in this face. Sleepy returns to the huddle, then a few minutes later, all the dwarves start running around laughing and chanting "DOPEY FUCKED A PENGUIN! DOPEY FUCKED A PENGUIN!"
