Talking Clock

After closing time at the bar, a drunk was proudly showing off his new apartment to a couple of his friends.  He led the way to his bedroom where there was a big brass gong and a mallet.

"What's up with the big brass gong?" one of his 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.
"It can't be a talking clock. How's it work?" the friend asked, squinting at it.
"Watch," the drunk replied.  He picked up the mallet, gave the gong an ear-shattering pound and stepped back.

The clock went: BONG-YONG-YONG-YONG-YONG-YONG-BONG !!!
The three stood looking at one another for a moment.

Suddenly someone on the other side of the wall screamed ....
"You a**hole!   It's three-fifteen in the morning!"
