A man is sat at home watching T.V. when he hears a knock at the door. The man gets
up and answers the door, to his astonishment there is a snail at the door. The snail says “can i
sell you some double glazing.” To which the man replies “no” and kicks him down the street.
Two weeks later there is another knock at the door. The man answers it and it is the snail
again. The snail then say “what did you do that for then.”
