An architect, an artist and an accountant were discussing whether it was
better to spend time with the wife or a mistress. The architect said he
enjoyed time with his wife, building a solid foundation for an enduring relationship. The artist said he enjoyed time with his mistress because
of the passion and mystery he found there. The accountant said: "I like both.""Both?" The accountant replied: "Yeah. If you have a wife and a mistress they will each assume you are spending time with the other woman, and you can
go to the office and get some work done."
