2x13 - Everybody Loves Raymond

Feeling left out when he thinks that his father selectively asked his brother to join a Civil War re-enactment, Ray voluntarily enlists for the Battle of Gettysburg. As the men prepare for Battle, a funny thing happens and Ray is finally able to tell Frank that he wishes they did more together. So, although Frank's on the side of the North and Raymond's on the side of the South, the Barone soldiers are able to put their political differences aside and share much more than a Civil War handshake.
