Talking Clock

Proudly showing off his new apartment to a couple of friends late one night, the drunk led the way to his bedroom where there was a big brass gong.

"What's that big brass gong for?" one of the guests asked.
"It's not a gong. It's a talking clock" the drunk replied.
"A talking clock? Seriously?" asked his astonished friend.
"Yup," replied the drunk.
"How does it work?" the second guest asked, squinting at it.
"Watch" the man said. He picked up a hammer, gave the gong an ear shattering pound and stepped back.

The three stood looking at one another for a moment.
Suddenly, someone on the other side of the wall screamed
"For God sake, you idiot ... it's ten past three in the morning!"
