Season One of Glenn Martin, DDS kinda passed me by, but I may have to start watching this season, if only for the guest stars. Last season's guest list was pretty impressive already (Alan Tudyk! Ty Burrell! Betty White!), but this season features guest vocals by Bret Michaels, Kristen Bell, John Corbett, Jim Parsons, Bradley Whitford, Seth MacFarlane and more. That's in addition to Kevin Nealon and Catherine O'Hara as Dr. and Mrs. Martin, of course. A show with that much talent can't be bad, right? At least, it can't sound bad, right?
