I'm playing along and I said Dr. Spock. Then I said, no wait, Mr. Spock is the fictional one. Then I see Spock on the board, and had to go back to hear the question again.
Regarding the question posed at 7:05 , I realize it's way too late to call shenanigans. But wouldn't "make a million dollars" -- given by Michael at 8:00 -- and "be a millionaire" -- given by Karen at 8:22 -- be the same thing? Those two answers were accepted before the memory aspect of the question kicked in.
