You can see the YEAH1993 sign at the VERY beginning of this video to the left of that big FEED ME MORE sign
Is that where you were sitting during SmackDown (dumb question prob but I'm not totally sure how this stuff works)? Did Lillian Garcia come ALL that way to ask what 'TLK' meant? I've been watching and Orton/Barrett just finished (yuck, btw) and I haven't spotted any of your signs.
Regardless of anything, a Yeah1993 sign made TV and my life has less pieces left to complete the puzzle.
