Back in grad school, we had an Algorithms Professor who was my advisor & wrote several important papers. We also had a PL professor who mostly taught Lisp/C/C++ etc. One day PL professor fell ill. So Algo Prof was sent in as a substitute. So he tried to divert the class attention by going into algorithm detail instead of focusing on programming language theory. But homework was due next week, so students asked him about some C nuance. So Prof said I don't know, but I'll let you know by next class. Then he hurried back to his room & tried to read up on C but obviously couldn't make much headway. In those days we had Usenet & that was it. So the Prof goes on Usenet & clicks on comp.lang.c. In those days I used to fancy myself a C hacker & I hung around on newsgroups trying to help out newbies. So I see this frustrated question from a newbie "HOW TO OPEN FILE FROM C ???" and I click on it so I can help this poor miserable bastard. Turns out it is from my Professor! The footer had his entire credentials like PhD, list of papers published, teaching career etc. So everybody on comp.lang was mocking this idiot who had a PhD in CS but didn't know how to open a fucking file with C. I was so embarrassed I rushed into his office & demanded how he could make a fool of himself like that. "You could have just asked me about fopen, why did you post in public that too with your real name ??! " He was like I've never used all this newsgroup stuff I barely know how to telnet. This was my first post I thought they will help me but they are just heaping abuse.
