It's Jeopardy! Kids Week. The kid in question was in second place. The picture above show what the Final Jeopardy question was. Thomas knew the answer. He just spelled it wrong... Watch video... 

The Jeopardy! producers ruled the misspelling a wrong answer! Did they do the right thing or should they have given this kid the points for a right answer?

BTW, not in a million years could he have won against the other boy, as you can see in the video...
