I remember one of my instructors in 1950 who had gone through the US training describing "hazing" and having to eat a "square meal" which consisted of sitting at attention, and presumably with the fork in one's right hand, loading it from the plate, stretching it away from himself, making a right angle turn, raising it to mouth level. bringing it back to his mouth and ingesting, lowering it back down to the plate, so when viewed from the side the fork would have described a square. All this supervised by the senior course. He told me this had originally come from West Point. I wonder if they still play these silly games?
