A joke.

Man really drunk late at night with his mate in the pub. They stagger back to the man's house and settle down in the front room to drink more. Mate notices a huge gong hanging in the corner and asks what it is. Man says it's a clock. Mate says how does it work? So man picks up a hammer from floor and in his drunken state eyes gong before giving it an enormous wack. The room begins to shake and the noise is tremendous, both man and his mate are shocked by the din. Suddenly a thumping can be heard through the partition wall and a muffled voice shouts. "It's three o'clock in the fucking morning!"
