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?"
Engineer: "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
plant and get some work done."
