An architect, an artist and an engineer were discussing whether it was better
to spend time with the spouse or a lover.
The architect said, "I enjoyed time with my spouse, building a solid
foundation for an enduring relationship.
The artist said, "I enjoyed time with my lover, because of the passion
and mystery I found there."
The engineer said, "I like both."
"Both?" they questioned.
The Engineer said, "Yeah. If you have a spouse and a lover, they will
each assume you are spending time with the other one, and you can go to
the lab and get some work done."
