This is not one found in very many stands, but I enjoy the teams that have the "chatter guy". He is like an extra infielder as he sits in the bleachers and exorts the home team pitcher with every throw to "hum babe", "show him the dark one", and my favorite, "Hum, pitcher, pitcher, swing!" His reply to what he considers a bad call is to quickly inform the pitcher, "Not your fault, keep firing."
A dieing breed, but a fan to be appreciated.
