Just for a bit of context...

In the fall of 1982 I was an exchange student at Northwestern University in Evanston, Illinois. One of the things NU was known for was having the worst college football team in their division. They hadn't won for a couple of years (I forget how long).

Anyway, one Saturday in October (I think) they played Northern Illinois University at home and won. The crowd, mainly comprising white, middle-class university students, invaded the pitch, tore down both goalposts, carried them out of the stadium, stopped at the house of the University President (who came out and greeted them), then carried them to Lake Michigan and threw them in. I still have pictures.

At the time I remember thinking if a crowd of British fans did that they would have been branded scum, hooligans, vermin and all the rest. When these Joe College kids do it it's a bit of fun.
