A guy gets talking to a girl in a club and they get on well, so they end up at his flat.
The girl's attention is drawn to a massive gong the guy has in the corner of his room. He says 'It's my timepiece. That gong lets me know what time it is. Any time of the day.'
The girl has no idea what he's on about so he grabs the striker and there's an almighty
BONNNNNNNNNNGGGGGGGGGGGGGGGGG!!!!!!!!!!!
Suddenly through the wall from next door's flat comes,
'FOR GOD'S SAKE NOT AGAIN!
IT'S QUARTER TO FOUR IN THE BLOODY MORNING!!!'
