Francois Barcomb, a high school physics teacher from New Paltz, won the "Jeopardy!" Teachers Tournament on Friday night.

He finished with a two-day total of $41,600, good for the $100,000 grand prize and a spot in the next "Jeopardy!" Tournament of Champions.

Conor Quinn, a world history teacher from Albany, finished second with a two-day total of $32,000. Sara DelVillano, a music teacher from Lanham, Md., was third with $19,600. Quinn's second-place prize was $50,000; DelVillano took home $25,000.

Once again, Barcomb was in the lead heading into Final Jeopardy, where the category was Photo Sharing. The answer was, "Publishing its first photo in 1889, today it has more than 4 billion likes & 100 million followers on Instagram."

All three contestants correctly wrote, "What is National Geographic?"

Barcomb played it safe, wagering $0, for a second-round total of $21,200. DelVillano also wagered nothing, staying at $14,800.

Quinn, though, went big, wagering $13,000 to finish with $26,400, enough to win Friday's match but not enough to win the tournament.
