Wife's Diet

[marval]

I walked in the pub yesterday and I couldn't help but notice a man sat at the bar scribbling on some paper and laughing hysterically.

"Why are you so happy?" I asked.

"My wife's been on a diet for the last four days, and she's lost five pounds." the man replied.

"What's so funny about that?" I asked.

"Well," he says "I've worked out that in four months, she will have disappeared completely!"

I can't see that as funny...
