Speaking clock

[dogblower]

Following a night out with a few friends, a man brought them back to
show off his new flat.
After the grand tour, the visitors were rather perplexed by the large
gong taking pride of place in the lounge.
'What's that big brass gong for?' one of the guests asked.
'Why, that's my Speaking Clock' the man replied.
'How does it work?'
'I'll show you', the man said, giving the gong an ear-shattering blow
with an unpadded hammer.
Suddenly, a voice from the other side of the wall screamed, 'For
****sake, you *****, it's twenty to two in the ****ing morning!!'
