I am a real pain in the rear because whenever a KIA says something really wrong. I say something about 'I don't think that is quite right' and look it up on the computer or my innumerable resource books I have around. I win! My friends say, "Uh-oh. Here goes Lucy again." I don't even get offended, because I'm usually correct. I am really awful about forwarding Snopes info to people who send weird misinformation. I am respected sometimes, and sometimes I notice those folks don't send me crap anymore. WIN!
Once I heard something about cashews, I looked it up before I argued, the speaker was correct, so all I to say was, "Gosh, Jim! Thanks." That one stands out. There are of course many other instances like that, because,sadly, I don't know eveything.
