Well, now, wait – I called Springer "an underdog to cheer for". I think that also covers O'Hurley and Hamilton as well, although I agree that "elderly" is a more obvious way to put it :).
The actresses? eh. I don't know how you can categorize Monique Coleman, who is brand new to the scene and star of a very popular recent movie, with Tia Carrere, who I don't think I've seen since Wayne's World.
I see on the Wikipedia page, by the way, that they note the same thing I did, although they include a "model" category (for Rachel Hunter and Tia Carerre) and call the Jerry Springer category "debonair old men".
