Do you know the difference between being completely blind and being legally blind when not wearing glasses? Good. You know who doesn't? Lysette Tidwell, a contestant on tonight's episode of Jeopardy! Tidwell? More like Tid-LOLWAT. All aboard the fail boat!

Before it came crashing down on her, Tidwell was on top of the world—she was the reigning champion; she sat comfortably in second place, with lots of time left to catch up; she had a first name that was almost as fun to say as "whilst." Tidwell was swell.

As you'll see in the video above, Tidwell even correctly answered the clue immediately preceding the one in question before her mea culpa—but what a mea culpa it was. This is the moment when Tidwell went from swell to what the hell?
