Amazing CLOCK

While proudly showing off his
new apartment to friends, a
college student led the way into
the den. "What is the big brass
gong and hammer for?" one of
his friends asked. "That is the
talking clock," the man replied.
"How's it work?"
"Watch," the man said and
proceeded to give the gong an
ear shattering pound with the
hammer. Suddenly, someone
screamed from the other side of
the wall, "Knock it off, you idiot!
It's two o'clock in the morning!"
