A man's sitting reading his newspaper when his wife comes in and whacks him on the head with a frying pan.

"What the hell was that for?" he asks

"that was for the piece of paper in your pants pocket with the name Mary-Ellen written on it." she replies

"Don't be silly," he says. "Two weeks ago I went to the races, Mary-Ellen was the name of one of the horses I bet on."

She seems satisfied and apologises.

Three days later he's again sitting in his chair reading when she hammers him with an even bigger frying pan, knocking him out cold.

When he comes around, he asks again, "What was that for?"

"Your #$%^& horse called."
