An italian architect, an artist and an engineer were discussing
whether it was better to spend time with the wife or a mistress.
The italian 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 lab and get some work done."
