The 'skirting board' is a piece of wood between the floor and the wall. Sometimes mice make holes in the skirting board.
What's the difference between a monster and a mouse?
A monster makes bigger holes in the skirting board!
Do you like this joke?
Thanks for your comment.
A mouse makes a small hole but a monster would make a very big hole. The joke is silly and funny because people don't really have a monster in their house.
