The landlord of a pub, is just locking up, when theres a ring on the doorbell.

He opens the door, and theres a snail sitting there. What do you want? asks the landlord.

The snail replies that he wants a drink.

Go away, were closed, and we dont 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, hes locking up again, and theres 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.
