Curb Your Enthusiasm's Cheryl Hines will guest-star on Scrubs as the sister of John C. McGinley's Dr. Cox. Per The Hollywood Reporter, Hines' character a devout Christian comes to town for the baptism of Cox's son. There's no word when the episode will air, since, well, there's no word when NBC will come to its senses and put Scrubs back on its schedule. But I'm not bitter.
