The Auctioneer is played by British actress Judy Geeson, who had co-starred in films with several A-list Hollywood stars (notably "To Sir with Love" with Sidney Poitier).
This episode mentions that Bill McNeal is childless (as he's wanting to adopt a child). However, off-screen Phil Hartman had two young children (Sean and Birgen) of his own. Interesting fact: of the original cast of 'Newsradio', all five male cast members have parented children of their own, while the three female cast members haven't had any.
