A man is in his house, it’s late at night and there’s a knock at the door… and he goes to the door, and it’s a snail. The snail says “I’d like to talk to you about buying some magazine subscriptions.” And the man is furious that he’s been interrupted, so he rears back and kicks the snail as hard as he can, slams the door, and goes to bed.

Two years later, there’s another knock on the door. He opens it, and it’s the snail, and the snail goes, “What the fuck was that all about?”
