Once a man went to a pet shop to buy a talking parrot. He saw a parrot with a red string tied to one of his legs and a blue one to the other.
He asks the shopkeeper, 'What are these strings for?'
The shopkeeper replies, 'If you pull the red string, the parrot speaks French and if
you pull the blue one he speaks English!'
The man asks, ‘Wow! And what if I pull both the strings?'
The parrot screams from the cage, 'I'll fall down, stupid!'
