Border Star 85 @ Ft Bliss went to the pilot's tent to check on a dead generator. Stripped off my BDU top to work on it, found the problem and went into the tent to tell my BMO (ex Armored Cav pilot) that I was going for the parts.
One of his rotorhead buddies said "Hey, Sergeant, you're out of uniform!" I said "Yes, sir! As soon as I find the flight surgeon I'll have him surgically attach a cot to my back."
Bet that left a mark...
