If you're around Mormons much, you know that folding arms and shaking hands is part of their culture. Just how much a part? Handshakes are very important elements of the LDS temple ordinances. And in the Doctrine and Covenants, Section 129 gives the vision-prone LDS people a test to know if a supernatural being who appears to them is from God or from Satan. (Offer such a being your hand. If he takes it, and you don’t feel anything, you’re in trouble.)
Even when I was a TBM (True Believing Mormon) I wondered why a demonic being wouldn't know to just not shake hands.
