I saw it, and I saw the guy on David Letterman.
It was okay... The guy plays a real first rate mutton-head, quite perfectly. I am kind of guessing this is the ole formula comedy, where the idiot goes on his quest, and experiences some sort of epiphany at the end of it.
I have to give my courage award to Taekwondo America, for allowing them to use the TA name and logo and so on. Might wind up being an okay promotional tool for them.
On the other hand... I expect this to be an excellent instructional video... on what NOT to do when you suit up and line up the students. LOL
