There are three parrots on sale in a pet shop.
A man's looking at them and asks, 'How much are these?'
'Well, this first one is £100,' says the shopkeeper.
'£100? Why so much?' says the man.
'He can squawk Beethoven and Bach. He's amazing.'
'What about that other one?' the man asks.
'£200 – he can quote Shakespeare and old poetry and everything,' says the shopkeeper.
'Good God,' says the man. 'And what about the last one?'
'What can he do?' says the man.
'Absolutely nothing,' the shopkeeper says. 'But the other two call him maestro.'
