...What are the moments that made you feel like, as a Reds fan, you wanted to crawl under a rock. Here are a couple that come to mind (top-of-my-head stuff)...in no particular order.
Marge. Overall I think she was great. A true fan. But she embarrassed us a few times (recylcing the flowers when the ump died, some of the stuff that came out of her mouth, and just her overall appearance--remember when she was on the cover of SI with that smoking cig? Yikes!).
Our offense (specifically Reggie Sanders and Ron Gant) against the Braves pitching in the 1995 NLCS. Whiff-city.
Jim Bowden makes my list. Dude had no couth. The way he fired Tony Perez, the way he treated Jeff Shaw, the leather pants...there are more, I'll just leave it at that.
Pete Rose...hate to say it...but it was pretty embarrassing when he finally came clean. I defended the guy. I still love him as a player but when he finally fessed up...embarrassing.
I know I'll come up with some more as I think further.
