Here’s another bit of WWII military humor.
A lieutenant fresh from jumping instructions was seated next to a sergeant in a parachute regiment during a night-time exercise. The Lt. looked very pale and frightened, so the sergeant struck up a conversation.
“Sacared Lieutenent?” he asked.
“No, just a bit apprehensive,” the lieutenent replied.
“What’s the difference?”
“Apprehension means I’m scared with a collage education.”
