Kenny definitely brought the funny. Who cares if he couldn't dance, his personality was enough to want to see him every week. Everyone on the show thought it was a crock he went before Master P. I wish they'd do DC every week during the results show. Heck, let him have Samantha's job.
Some other names to add to the speculation list: Kathy Sledge (of Sister Sledge fame) and Donny Osmond. Donny has been bringing his name up as being interested, then not, then saying he's going to be on, then saying he's game the next season, since Marie made her dancing debut. I don't mind Donny but one Osmond was enough for me. Since the show is even now in terms of male/female winners, and the last 3 winners have been female, I fear the show may be going for a male winner next year and Donny might be it. Oh well, as long as it's Edyta or Kym that gets him, I wouldn't mind if he wins. There's also rumors about casting ladies from The Real Housewives series. Of all the names mentioned so far, I hope none of them are true. I know last season was a pleasant surprise despite not being crazy about the cast pre-show, but if these people wind up being the majority, I think it'll be a train wreck. I just hope Derek, Cheryl, and Mark (and FWIW, it's been rumored on the ABC boards his girlfriend wants to join the cast) get clunkers and early exits next season, and some of the other vets that have paid their dues go all the way. I'd like to see all fresh faces in the finals and semi finals next time.
