Over a beer

Over a beer one evening, Fred was going on and on about his mother-in-law - how cheap was, how meddlesome, how petty, how overbearing, how boring.

But then he leaned over and confessed that he had to give the old bird credit for one thing. There was one moment when he'd have cut his throat if it weren't for her.

"Huh?" His buddy was startled.

"She was using my razor."
