A man walks into a pet shop to buy a nightingale as he loves the song they make. "I'm sorry sir, selling nightingales is illegal. I can sell you a canary, and if you drill two small holes in the top of the beak it will sing just like a nightingale'
The guy thinks the shop owner is a nutter so leaves and goes to a second pet shop. He asks for a nightingale, but again he is told; "I'm sorry sir, selling nightingales is illegal. I can sell you a canary, and if you drill two small holes in the top of the beak it will sing just like a nightingale' "I can show you exactly where to drill the holes, and I have canaries at a very good price."
Intrigued he buys the Canary and the pet shop owner gives him a diagram of where to drill the holes. " But be careful, if the holes are 1 millimetre out then the bird will drown when it has a drink of water".
The man goes to a tool shop and explains he wants a very fine drill bit. The tool shop owner asks why, and the man explains about the canary and the fine drilling. "I've heard of this" says the toolshop owner "but I hear you have to be very accurate, if you are more than 1 millimeter out, the bird will drown the first time it tries to drink water."
The man pays for the drill bit and heads home.
A few days later the man is back in the petshop to buy another canary. " What happened?" asks the owner, " Did you drill the holes in the wrong place?"
'I don't know' says the man ' the thing was already dead when I took it out of the vice.'
