An architect, an artist and an engineer
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 engineer said, "I like both."
"Both?" they ask.
The engineer replies, "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 lab and get some work done."
