Let's start with the fact that I live in Gainesville, FL (originally from Sharon, MA and my father played for the state title in the old Garden).
So I am going to a Super Wal-Mart (don't kill me) and as I am pulling in wearing my 4 year old C's hat (which I had custom embroidered with "The Truth" on the side) and sporting my Celtics front-plate that my Dad bought in 1997, I hear some guy walking with his kid past my car say "Jumping on the bandwagon I see".
I slammed my brakes, put the window all the way down and said, "Excuse me?". He said "Oh, jumping on the bandwagon I see". So I said, "Yeah, actually I was a shareholder from the day I was born until the day they sold the team in 1992, but thats a great way to teach your kid how to talk to people he doesn't know."
He shut up pretty fast, but it's so funny. I have lived here for 12 years and had that same plate on my car the whole time and not a single person ever said anything 1 way or another about it (maybe a few pity comments). But now, I'm "on the bandwagon". Priceless.
