Aggies vs Bears
No hate, just fun. "What's a matter, couldn't get into Davis?" is what Dan Hawkins said to Chancellor May the other day when they renamed Aggie Stadium (May went to UC Berkeley). It's a play on how all of us at one point were asked why we went to Davis instead of Cal. Both schools are excellent and Davis' reputation amongst college applicants now is higher than ever.
"State School" is usually reserved for schools with the word "State" in their name, like they're bad. But really it's silly because both Davis and Cal are state-funded universities... So I'm poking fun at that notion of superiority as well.
"Kal State Berkeley" is fun because, as much as we hate being referred to as "Cal-Davis," Cal people hate it even more to add anything else after "Cal" or "California." Again, another tease, but not trying to put anyone down.
Really, they're inside jokes for those who like dumb signs.
