Card game.

A man came home from a poker game late one night and found his hideous harpy of a wife waiting for him with a rolling pin.
"Where the hell have you been?" she asked.
"You'll have to pack all your things, dear," he said. "I've just lost you in a card game."
"How did you manage to do that, genius?" she asked sarcastically.
"It wasn't easy, honest," he told her. "I had to fold with a royal flush."
