Speaking clock

An irish bloke takes his mates back to see his new flat, and after a few more beers one of the lads asks him whats the big brass gong hanging on the wall, Paddy says Its my speaking clock ! How does it work? I'll show you, and he hits it full pelt with a claw hammer, And a voice from next door yells"For f#%ks sake its twenty to three in the morning!!!
