The Snail

A guy hears a knocking on his door. He opens it up,
and no one is there. He looks all around and he finally
sees a little snail sitting on the doormat. He picks
it up and throws it across the street into a field.
Ten years goes by, and one day he hears a knocking on
his door. He opens it up and no one is there. He looks
all around and he finally sees the little snail sitting
on the doormat. The snail says, "What the %$&*# was that
all about?" ;D
