Air Arms Owners Club

Mr. Brown was working in his garden when on the other side of the fence, he heard his neighbor crying. Mr. Brown popped his head over the fence and asked, "What's the matter Mary? What has upset you?" The blonde neighbor replied, "My dog has died and I'm going to bury it here." Mr. Brown said, "You only have one dog, so why have you dug three holes?" She answered, "The first two were too small."

That is like Isaac Newton and the 2 cat flaps on his door .... one for the mummy cat and smaller one for the kittens.
