Anyone find it strange that our Commander in Chief doesn't know what a Navy Corpsman is?

Yes, but he isn't military oriented. What I find stranger is that an educated man doesn't know the difference between "corps" and "corpse" in general, remember the FDR Civilian Conservation "Corps", how about Kennedy's Peace "Corps". I think Clinton also started some sort of Leftist "Corps", it's a word that isn't just used by the Military (it was easy to think up 3 Socialist examples). Even stranger is that if he is so smart that he doesn't have his teleprompter writers spell things out phonetically and/or rehearse his speeches.
