After going through the house the girl notices there's a giant gong and a mallet in one of the rooms.
She asks, 'What's the deal with the gong?'
He replies, 'That's not a gong, its a talking clock.'
She is amazed and asks how it works.
The man proceeds to whack the the gong with the mallet, the two of them stood looking at one another for a moment.
Suddenly, someone on the other side of the wall screamed, 'HEY MAN!, it's three fifteen in the bloody morning!'
