Not sure if it's what you're referencing, but my favorite Harry's graffiti was:
I'm talking about the marquee outside. They put it up shortly after we beat UF in 1993, and it stayed up until Bowden resigned.
And my favorite was over the toilet, "FLUSH TWICE, IT'S A LONG WAY TO TUSCALOSER."
God, I miss that place, the T-Shirts they would make every year were great. We went back in 1998 or 1999, and they had shirts that read, simply, "HARRY'S BAR - Proverbs 31:7"
So the first thing we did when we got back to the hotel was bust out the hotel bible, and then went back the next night to buy one of those shirts.
