It seems like NBC has been dying for DonD just to have a show to overpromote their own stuff all over. Thank God Celebrity DonD would be virtually pointless.
Wrestlers do tend to make for fun contestants to watch, though. In addition to Savage, the WWF Weakest Link (Yes, it was WWF back then) was pretty entertaining, and Diamond Dallas Page made for an entertaining Hollywood Square. However, Hogan, any time he's out of the ring, is generally pretty bland.
I'm sure there will be a Saturday Night's Main Event commercial or two during the show. However, you'd think that they would pick a guy that most people actually might know. (I know, I know, this really shouldn't have even happened) I barely know Nunzio, and I'm a pretty big wrestling buff. Never got to see a PPV, but I saw 2 Nitros, 2 Thunders, 2 WCW house shows, and a Raw in Cleveland.
