I think you could add in here AJ's go-ahead homer agains the Cubs in 06 to the list...the one where the fans started throwing trash on the field. That one was pretty sweet.
I also think you could add Thome's 500th bomb to the list as well, simply because of it being a walk-off and the way Hawk called it.
I don't think either of those are #1 though...#1 belong to either Paulie or Scotty Pods.
Oh and a couple other memorable ones, Konerko and Dye both hitting #300 (or was it 400?) in the same game against Detroit I believe. That was pretty special.
