My parents have lived in Baton Rouge for 20 years now. My dad (Auburn '67 and '73) is a VP for an Environmental Engineering firm there in BR, having 9 or 10 people (all LSU grads) reporting to him.
Several years ago, my dad bought a very obnoxious Auburn tie that plays the fight song. He wears it once a year, the Friday before the Auburn/LSU game. He calls a staff meeting for about 2:30, walks in 5 minutes late, sits down, plays the fight song, and then gets up and leaves, saying, "War Eagle."
