I've never been to one of these high-profile spelling bees, though I've watched parts of some of them on TV. I don't recall ever seeing or hearing anything in the any of the Bees I've watched that made me chuckle, but there are moments like this at times.
The first one I'd heard about was a couple of years ago (and very intentional). A contestant decided to lighten the mood with his Napoleon Dynamite impression.
The commentator, painfully out of touch, had no idea what was going on. "Was that a secret message?"
I just heard about this one today. A contestant actually misheard a word and inadvertently brought the funny.
Hilarious...."numbnut?"
Oh, and Akilah and the Bee is a fantastic movie. It's a good one for kids, too.
