I shouldn't pick on this poor guy. Lord knows that there have been plenty of times that I've only seen a word, never heard it pronounced, and didn't know how to pronounce it.
Nah, I should make fun of him. When that happens to me if I don't know is I ask someone the correct pronunciation, or look it up. I did this recently with "inchoate." I did that just so I'd use it properly in conversation; I think if I was going to speak on a video available on the World Wide Web I'd really check out any word I wasn't sure of.
So, you don't have to watch all this video, which is otherwise essentially information-free infotainment, but do watch up to the pretty boy try to use the word "hyperbole" at about 1:01 in.
Maybe this guy needs to turn this into a thing -- the day after the Superbowl host a HyperBowl giving out awards for those able to generate the most hype out of a campaign with some obvious exaggerations.
