Reminds me of when I went to a Montreal Canadiens-New York Rangers game at the Forum in about 1982
I was at a Notre Dame-PSU game at State College one year...and the anti-Catholic vitriol I had to hear from the surrounding drunkards was beyond belief...the way it goes, I guess...
I was at a ND / Purdue game one year and a kid came up the stairs with a t-shirt that read F_CK ND
A guy jumped up from his aisle seat and told the kid to take it off. The kid smarted off to him and the guy grabbed the shirt at the collar and literally tore it in half to the bottom hem.
Never seen anything like it LOL.
