One of my proudest moments, actually...
I had recently graduated from UC Santa Barbara, living back in Orange County, and my Gauchos were traveling south to face the USC Trojans. This was in 1997ish, so the OJ Simpson stuff was still fresh in everyone's mind. I traveled north up to LA to the Sports Arena, where the Trojans called home.
The dolts at SC had handed out these signs to the entire arena that said "GO TROJANS".. even to the "visiting" side. Fairly large signs... maybe 15" x 20", so you could see them from a distance.
I ripped off the bottom corners, removing the "TR" and "ANS", so it just said "GO OJ". Held that sucker up for awhile and saw the Trojan band from across the arena start pointing and laughing and actually gave me a round of applause for my ingenuity.
