Paddy walks through town one day when he spots an interesting looking box in a shop window.
He enters the shop, grabs the box and gives it a shake.
Paddy thinks to himself 'God, this must be some sort of million piece jigsaw'. He buys the jigsaw.
When he arrives home, he pours the jigsaw out across the table. But all of the pieces are the same. Paddy tries turning them over but they still all look the same. So he decides to ring up his mate Patrick.
'Patrick I've got a bit of a problem. I've bought this million piece jigsaw and all of the pieces look the same.
'Well have you tried turning them over Paddy?'
'Yes, yes I've tried that and they still all look the same.'
'OK I'll come round to your house in a minute, but tell me one more thing, what's on the front of the box?'
'Oh, some sort of cockerel.'
When Patrick arrives at Paddy's, he takes him through to the living room where the jigsaw is laid out across the table.
'You see Patrick, this is my million piece jigsaw with all the pieces that look the same.'
And Patrick says...
'Paddy, that's a box of corn flakes!!!'
