Paddy and Mick go to a rugby match.
At the entrance Mick searches everywhere but can't find the tickets.
Paddy says Mick "Nip home and see if I left the tickets there."
"No problem" says Paddy.
Half an hour later Paddy returns to Mick who is patiently waiting outside the stadium.
"Did I leave the tickets at home?" asks Mick.
"Yes," says Paddy.
