Oh, the Germans! I told one a joke once during a de-brief, a joke based on that old one about the "Curate's Egg," saying that my last approach had been "good in parts." Sort of like "Straight and level ... so which one do you want to see first?" except that he thought I meant it straight.
It went right over his square head, of course, and when the CP cleared his throat and said "I believe you may find that Captain [chuks] was making a joke there," the jerk went all Krakatoa on me, starting with "I know that iss a joke!" and going on from there, really losing his rag. I ended up wondering if I could make him fit out one of those funny little narrow windows in the briefing room if he did not stop "yabbing me" then, but I wandered off to drink a glass of water instead of ending up in a Dutch hoosegow.
