Final appearance of Noble Willingham as CD Parker. Said character would not be seen or mentioned again until the following season, with "Avenging Angel".
An early draft of the script for this episode had CD being killed off by the "Santa Gang"; ultimately, Gordon Cahill (Alex's dad) - who's in town for a visit - buys up CD's Place, which is renamed "The Big Dog Bar & Grill" in his honor. A life-size portrait of CD is placed over the bar, in an ebony frame, with a candle underneath. All of this, intended to make Gordon a regular character on the series, was dropped in rewrites...because the producers considered it too depressing for a special Holiday episode.
