An insurance man knocks on the door of a house.
The owner is out - so the parrot answers the door, and asks, 'Who is it?'
'The insurance man.'
'Who is it?' says the parrot.
'I told you - the insurance man.'
'Who is it?' the parrot repeats.
This goes on seven or eight times. And eventually the poor insurance man has a heart attack and collapses and dies on the doorstep.
The owner of the house comes back and sees the dead insurance man.
'Who is this?' the house-owner asks the parrot.
'Oh, it's the insurance man,' says the parrot.
