Maybe to justify their stance on not wearing spandex pants, they will point to the great pyramid of Giza in Egypt and also the Soviet space satellite “Sputnik 1” and say something like this:
“Well, we can see that none of the mummies found in the tombs were shown to be wearing any spandex products. Of course not! Why? Because, according to the encyclopedia, ‘Spandex or elastane is a synthetic fiber known for its exceptional elasticity. . . . It is a polyester-polyurethane copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia.’ And, as you know, 1958 was a year which overlapped the 12-month year period beginning on October 4, 1957, on which day saw the launch of the first artificial earth satellite, called ‘Sputnik 1,’ which the Soviet Union launched into an elliptical low earth orbit – thus ushering in the age when strange sights would be seen in the heavens; i.e., the space age. So, therefore, is it not logical to conclude, brothers, that this worldly and debased spandex stuff was never intended by Jehovah, as clearly none of the mummified corpses we see in the Egyptian tombs in the pyramids have any traces of it, and also the year of its invention, 1958, overlaps the 12-month year period beginning in October 1957, the year which saw the introduction of those strage sights in the heavens? So, would spandex be something for Christians? Did Jesus ever wear spandex? Govern yourselves accordingly, brothers!”
Ya, I can just hear them saying something like that to try to justify their usual not-so-iron-clad reasoning.
