A farmer hears a knock at his door late one winter’s night. He opens his door, looks around and looks down and there, at his doorstep, is a snail. The snail says, “Can I come in, I’m really coooooold?” The Farmer says, “No, get outta here you stupid snail,” and kicks him across the garden. Spring comes, then summer then fall and before you know it, it’s winter again. The farmer hears a knock on his door. He opens the door, looks around and sees that same snail from last year, who says, “What did you do that for?”
