Case in point on Tuesday’s episode, which was guest hosted by Big Bang Theory actress and neuroscientist Mayim Bialik. When contestant Robin Lozano chose the “Quotations” category for $800 during a round of Double Jeopardy, the clue read: "'Government of the people, by the people, for the people' is from the end of this brief but powerful speech.” Seconds quickly passed before the buzzer went off. It turns out, neither Robin nor her fellow competitors Kevin Hirsh and Dominic Rios knew the correct answer . While Maiym revealed that the line was from President Abraham Lincoln’s Gettysburg Address and moved onto the next clue, folks watching from home didn’t easily forget the moment.
