After a late night of partying, a guy invites his friends back to his new apartment.
While he is giving them a tour, one of his friends notices a huge gong and hammer near the wall.
"What's up with the gong?", he asks.
"Oh that's not a gong, it is a talking clock."
His friends voices skepticism, "Dude, that's not a talking clock, it's obviously a friggin' gong."
The guy replies, "No, I swear, you hit it with that hammer as hard as you can and it tells you the time. Go ahead, give it a try."
His friend shrugs his shoulders, grabs the hammer, rears back, and strikes it with a loud: "GOOOOOOOOOOONG!"
After a few seconds they hear a voice from the other side of the wall, "Hey asshole! IT'S THREE-THIRTY IN THE FUCKING MORNING!"
