That does my fucking head in when you get mini managers sitting behind you. I was at a St. Johnstone/Partick Thistle game a few weeks ago and I swear to god, the guy behind me would not shut his fucking mouth for two seconds. Fair play, we're all entitled to have a shout and a moan, but this guy was unreal.
Speaking of racism, I heard the best thing a few years ago. A black player from the away went in hard on one of our players and didn't get booked, the guy in front of me shouts, without a hint of irony, "He only got away with that because he's ethnic!". It tickled me just right.
