. (e.g., if a clue is asked about the title woman in a Beatles song comes back with "Eleanor Roosevelt" instead of "Eleanor Rigby," all it would take to prove that it couldn't be Eleanor Roosevelt is a list of Beatles song titles.)
I know this is just an example, but let's roll with it. If you're asking whether a player answering "Eleanor Roosevelt" would make the judges go and search a list of Beatles songs to make sure there wasn't one called "Eleanor Roosevelt", no, they don't do that. If on a commercial break, the player says "I'm pretty sure there was a Beatles song called 'Eleanor Roosevelt', could you check and make sure?" then they'll check and make sure. Also, if one of the writers or judges or producers or whatever says "You know, I seem to remember that Ringo might have recorded an album about first ladies, maybe we should stop and look that up," then that will happen too. But it does not happen for every single wrong answer that's supplied by a player.
