I showed the hand sign to the painted GOUL guys and I got them to pose all showing it.
I showed it to Cayenne (El Sidonio on RP) at a Tennis match (out of costume) He started doing it at games.
I use to stand in the tunnel after games holding the UL hand sign up and the football players would shoot it back.
However, I have almost six thousand pictures I took at practice, events, media day, post game, between 1999 and 2003 and not one player or fan was showing the UL hand sign.
I have thousands more pictures I took from 2004 to 2008 before David Walker kicked me out. By then it had caught on nd I have lots of UL hand signs in those years.
