One should always keep one's ear cocked in the presence of sergeants-major, one never knows what novel abuse they will coin. Our BSM was passing on instructions to the NCOs near the battery kitchen one day late in 1976. Wanting some coffee and realizing he was without cup, he turned to Hutchison, the battery clerk, and instructed him to retrieve it. Hutchison hiked off to the wagon lines, whence we heard the burping and farting of the BSM's ancient 3/4 ton truck "Sadie" firing up. Hutchison faithfully followed the track plan, eventually arriving in Sadie at the battery kitchen. When he halted, the BSM could be heard bellowing, even at the far end of the gun line, "You saucer-headed c*******er, I told you to bring me my cup and you brought me my truck. You ****ing saucer-head!" And so "saucer-head" passed into battery, then unit, then regimental parlance, and is still occasionally used on people with apparently vacant brain pans anywhere in the Canadian artillery.
