Bachelors have consciences, married men have wives.

Though bachelors be the strongest stakes, married men are the best binders, in the hedge of the commonwealth.

Bachelors know more about women than married men; if they didn't they'd be married too.

I don't sleep with happily married men.

All men make mistakes, but married men find out about them sooner.

I do not think you can name many great inventions that have been made by married men.
