I resemble that remark!
My husband has driven a few realtors around the bend, but the funniest thing that he does is at antiques shows. The reason that it is so funny is that he is not trying to be funny. We collect 18th century antique furniture (when we can afford it). More than once I've seen him drop down on the floor at a big charity show, pull out his flashlight and magnifying glass and start examining the underside of a piece of furniture. Usually a crowd starts to gather, and then he proceeds to expound on new wood, old wood, reasonable wear, repairs, etc. The salesman is just left standing there with his mouth open while everyone is ooohing and aahhing and nodding and I stand there trying to melt into the floor.
At the fanciest show in Chicago one year he proclaimed 4 expensive high chests to be "fakes". When I say, proclaimed, I really mean "muttered" his observations into my ear. Then he started questioning the seller very carefully. The seller wouldn't give an inch on the authenticity and age of his wares. My husband had good reasons why these pieces were not 'right'. Sure enough, a year or so later, we read that the dealer had been sued by an unhappy (read cheated) Chicago buyer of these chests of drawers and run out of business. My engineer husband felt vindicated because he had spotted the phony goods first, and none of the dealers and collectors at the show would confirm his observations.
That is one of the big differences between engineers and ordinary people. Engineers have developed their powers of observation of physical properties to a fine art. (They are not as good at observing emotional qualities in the people around them, and that is how they get crosswise with wives and co-workers.)
