I just watched a clip on Nashville SC and how they cut a vinyl of the game commentary for their MOM.

The Timbers slice off a piece of log. New England fire 1700's muskets. Montreal rings that awful bell. Seattle have their band marches. There probably are others that don't immediately come to mind.

TFC, gimmick-free since 2007. No mascots. No cheerleaders. Just a team with solid support by people who don't need cheap gimmicks.
