The landlord of a pub, is just locking up, when there's a ring on the doorbell.
He opens the door, and there's a snail sitting there. "What do you want?" asks the landlord.
The snail replies that he wants a drink.
"Go away, we're closed, and we don't serve snails anyway".
The snail pleads and pleads with the barman to give it a drink, at which the landlord gets fed up, kicks the snail and slams the door.
..... Exactly one year later, he's locking up again, and there's a ring at the doorbell. The landlord opens the door, and looks down to see a snail sitting there. "What do you want" says the landlord.
"What did you do that for" says the snail.
