There is an accident on the construction site. Seamus runs over to where Paddy is lying in a heap of rubble.
“Are you dead, Paddy, after such a terrible fall?” asks Seamus.
“Yes, certainly I am,” replies Paddy.
“Ah, bejabers!” says Seamus, “you are such a terrible liar, I don’t know whether to believe you or not.”
“That proves I am dead, you idiot,” says Paddy. “If I was alive, you would not be calling me a liar to my face.”
