Not to be out-done, they decide to walk to Larry’s place for a few more beers.
The first thing Mick says when he staggers inside is: “Hey Larry, you haven’t got a clock in this house so how do you know the time when you get home?”
Larry says: That’s easy, I play my trumpet.”
Mick says: “Your trumpet? How on earth can you tell the time from your trumpet?” And Larry starts playing the trumpet and one of the neighbours shouts: “Stop playing the damn trumpet… it’s 1.30 in the morning!”
