Yeah, the Old Firm, two cheeks from the same arse as the saying goes. The ever lovable Ally McCoist went full Neil Lennon at one point demanding to know the names of a trio of people on a panel who dared vote to place a year long transfer embargo on them, which then led to the names being leaked and death threats being thrown there way. Then you have the recent nonsense over a potential penalty that was offside anyway that they refuse to let go, apparently they have heard the audio and it contains no mention of the offside. Obviously the lack of communication at the game was poor but the video evidence is clear as day.
One thing I find hilarious though about Old Firm fans are they know each others business, a Celtic fan I work with was raging about the shirt pull they got away with against us on Christmas Eve and provided me with evidence of a certain David Dickinson giving them one earlier this season against Morton for a slight tickle.
