On this day in 1798, the first brawl in the US House occurred when Rep. Matthew Lyon (DR-VT) and Rep. Roger Griswold (F-CT) fought each other on the House floor after Lyon spat in Griswold's face.
Lyon later served in the House from both Kentucky and Arkansas, and is the only person in history to represent three different states in the US House of Representatives.
He was so classy, three states voted him into the House... when it comes to the US House of Representatives, apparently some things never change...
