An artist, architect, and engineer are at a bar... ...talking about having a wife vs. a mistress. The artist declares that he prefers a mistress because he finds them more spontaneous and exciting. The architect says, ""no, I much prefer a wife because I enjoy building that foundation with one woman and love the security that comes with marriage."" The engineer says, ""I prefer to have both and to spend equal time between the two of them... eventually, they both get used to you not being around and you can sneak off and get some work done.""
