Tonight the Phillies are playing the Washington Nationals.
I think it's worth mentioning that the Nationals have a pretty cool tradition at their home games that has great historical significance.
Much like a minor league baseball stunt, to keep the fans entertained between innings, there is a Presidential race. Only this race involves four mascots representing the four presidents on Mount Rushmore.
Every game, George Washington, Thomas Jefferson, Abraham Lincoln and Teddy Roosevelt compete. The race originated as a scoreboard graphic, but has morphed into the "live-action" race pictured above.
There is a running joke that Teddy Roosevelt never wins. He'll often become distracted, or become disqualified for numerous reasons.

By the way, the Phillies are currently winning 6-3 in the 7th.
