They wanted to make sure nobody had fun, lest it hurt the feels of the asshole community.Argos also have a cannon.
They also have 5 people running with 5 flags up and back on the field with flags that spell A-R-G-O-S. Until last year the Letters were visible on both sides of the flag so one side of the stadium saw S-O-G-R-A. People used to cheer that. It was kind of fun. Then they replaced one half of the flag with a generic Argos logo and took away the fun.
