My dad was a serious intellectual ogre, and loved to play status games with people based on proving he was smarter than they were. The fact that he did this with his children just proves what an asshole he was, but never mind.
At any rate, given that situation, it’s not surprising that I remember one specific period during which I embarrassed him not once, not twice, but three times in a single month.
First: We all wanted to go see the movie F/X. (Yes, the one with Bryan Brown, from '85 or thereabouts. This sort of dates me, I know.) My dad asked me if I knew what that stood for. I said, “Uh, yeah, it’s a filmmaking shorthand term for ‘effects.’” (I’ve been a movie geek since way, way back.) He looked at me smugly, and said, “No, it means ‘factor experimental.’” I told him he was wrong; he just kept acting smug. Then we went and saw the movie; right after it ended, I dug out the copy of Starlog I had brought with me, and showed him a cite. He was pretty humiliated.
But that’s not all.
Second: Two weeks later, we were watching TV (I think), and someone came on with a neck injury, wearing one of those padded collars. My dad referred to it as a “clavical” collar. I said, “Um, no, it’s a cervical collar.” He disagreed, getting all smug again, and said that only a woman has a cervix. I shook my head, and I said, “No, the back of the neck is called the cervix also. That means a woman has two.” I had to go get an anatomy book to prove it to him. He was, again, chagrined.
And then…
Third: Two weeks later, I checkmated him. Yes, for the first time. He was absolutely shocked. As it turned out, it was also the last time I checkmated him, because he absolutely refused ever to play chess with me again.
Like I said, he valued his intellectual prowess above all else. Any threat was not to be tolerated. (Asshole.)
