A man and his wife are at a restaurant…

The wife leaves for the bathroom and a short while later the waiter arrives.

'what would you like sir?' he asks.

'I'll have the steak, but my wife is using the restroom at the minute', the man replies.

'oh, well, do you know what she's having?'

The man replies, 'well it's been about 10 minutes so I'd say a shit'
