Two mates return to one blokes apartment after a long night of drinking and partying. The guest notices a giant gong on his hosts living room wall, and inquires about it.
"Oh, that's my talking clock", answers his host.
"A talking clock??, his mate replies. "Doesn't look anything like a clock to me, let alone a talking one?"
"You don't believe me? Look, I'll show you!", his mate replies.
He walks over to the gong, picks up a big lump of wood, swings it, and hits the gong with all his might. "BOOOOOONNNNNNG!!!!!" rings throughout the building.
Immediately, from the apartment next door, a voice screams out, "For f***'s sake!!! - it's 2:45 in the morning!!"
