Forum:Superintendent Chalmers insulting Principal Skinner

I like looking into tv characters and try to understand the the philosophy of the characters. The character that I have been looking into is principal Skinner and I have learned a lot about his history and background, and his character. But there is one thing that I notice is missing in his biography that I cannot find anywhere. One time I seen an eppisode where superintendant Chalmers was going down a list of insults and comlaint about Skinner and I think one of the comments was the way he wears his suit to which Skinner responded by saying something about how he has uneven shoulders I think. I don't remember the scene fully since I only seen it one time and I do not even know the episode that it is from. Do anyone know what I am talking about? and if so can you tell me what eppisode it is from? Thank you.
