In this episode, Dr. Sloan tells Steve about the time his brother went chasing after him with a nine iron while sleepwalking as naked as a jaybird.
Additionally, guest star Garrett starred on new exec producer Chris Abbott's previous series Legacy.
Ironically, Jerry Van Dyke also played a character with a sleepwalking problem in an episode of his brother's classic 1960's sitcom The Dick Van Dyke Show.
In a late 1998 issue of Mystery Scene magazine, Dick Van Dyke said the following ... "...I've tried to get my brother (to appear on the show), and I can't... Jerry just hates one-camera shows. He much prefers doing three-camera situation comedies. He says, 'I get so bored, sitting around with those one-camera shows. They drive me crazy... So I can't talk my own brother into doing the show. It could be great. I told him he could play Mark Sloan's loose-cannon brother."
