A friend of mine lives on a farm in the middle of nowhere, they have a pet cat called Nelson because he has one eye. One night they are sitting in the lounge watching a horror movie on TV and they hear a tap on the window.
"No way am I opening the curtains to see who that is"
"Ummm, OK, because I don't want to look either, perhaps they will go away"
Tap, tap, tap.
"Damn, they're still there, go and have a look"
"No chance, you see who it is"
Tap, tap, tap, tap, then there is a weird noise.
"OK, we'll both go together, ready?"
"Ready, 3-2-1-GO!"
So my friend and his wife both throw back the curtains and there's Nelson hanging on to the wooden window frame with his front paws whilst banging on the window glass using his back feet.
