A young lad was proudly showing off his new apartment to a friend. The college student led the way into the living room where the friend noticed a large gong and hammer sitting against one wall.
“What’s the big brass gong and hammer over there?”, the friend asked.
“That is a talking clock,” the lad replied.
“Really, how does it work?”
“Watch, ” the lad said and proceeded to give the gong an ear shattering hit with the hammer.
Suddenly, a voice screamed from the other side of the wall, “Knock it off, you idiot! It’s two o’clock in the morning!”
