A mouse walks into a music shop and asks the shopkeeper “Have you got a mouse organ?”
The shopkeeper replies “No”.
The mouse walks off.
The next day another mouse walks into the music shop. “Have you got a mouse organ?”
it asks.
“No,” replies the shopkeeper,
“but it’s funny you should ask as there was another mouse asking for the same thing yesterday.”
The mouse nods and says “Oh yes, that’ll be our Monica”.
