These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
They Just Didn't Care: On May 3, 2007, the correct answers to two separate questions in the same game were inadvertently muttered loud enough for the contestant to hear. The $2,500-question in 1st Grade Music asked which of the following was a percussion instrument: A. Viola, B. Xylophone, C. Bassoon. The correct answer was B. The $175,000-question in 4th Grade World History asked to identify the picture writing used by ancient Egyptians: Hieroglyphics. Neither question was thrown out and the contestant quit with $175,000.
Ashley McCohn, who lost the game on her first question! The funny part came when the producers seemed to like her personality enough to force Wayne Brady to come in and invite her to appear on sister show Don't Forget The Lyrics. Unfortunately she faced a similar fate, losing on the $10,000 level when she picked a category containing Title Theme Tunes she had never heard of.
One contestant didn't know how "vowel" is spelled when the question was how many consonants in that word. She thought it was "voul".
Another contestant horrifically flubs the first question (1st grade health), which asks if the esophagus connects the mouth to the nose (It actually connects the mouth to the stomach). The guy answers true and he is a freaking pre-med student! If it weren't for the Save, he would have been eliminated on the very first question. Of course, the host takes a jab at him by saying "Thank god you are not my doctor!" and "Did you go to any of your pre-med classes while you were there?"
