A fellow team alumnus and I went to visit our team at the beginning of build season. Our engineer mentor had cut tetra joints out of a plastic that was stiffer than the joints provided in the kit, so we had to use a torch to heat the plastic and make it more flexible. While assembling a tetra, my friend had unknowingly put his crotchal area in contact with a still hot plastic joint. The cursing and ridicule that followed are inappropriate for posting, but I remember it as one of the highlights of the season.
