What time is it?

Proudly showing off his new apartment to a friend late one night, the drunk led the way to the bedroom, where there was a big br gong. "What's that br gong for?" asked the friend. "It's not a gong. It's a talking clock," the drunk replied. "A talking clock? How's it work?" "Watch this," said the drunk. He took a hammer, gave the gong an ear-shattering pound and waited. Someone on the other side of the wall screamed: "Hey, you jerk. It's 3:00 in the morning!"
