In basic (long story short) I hyperventilated while trying to get a late slip for sick call (ended up I had pneumonia). Anyway, a drill from another platoon drove me over to sick call in a cattle car, me in the passenger seat. His cover was on the dash, and as he made a left turn it slid off and started to go out the window... command decision time, so I grabbed it.
And IMMEDIATELY replaced it on the dash as he looked about to rip my lungs out. He opened his mouth, clenched his teeth, and slowly grated out the words "Thank you". See, they are human, sort of.
