In this episode, Gary (Erica's father) wears a shirt with a drawing of the Vulcan salute and the Vulcan greeting "Live Long and Prosper" on it. This has a double meaning. Presumably, it means that Gary is a fan of the television series "Star Trek" and its spin-off series and movies. But it is also a reference to Gary's profession; Gary is a rabbi, and the Vulcan gesture was created by Spock actor Leonard Nimoy, who took the hand motion from a ritual gesture that is a traditional part of a Jewish prayer called the Birkat Kohanim. Nimoy, the son of Orthodox Jewish immigrants from the Ukraine, grew up seeing the gesture performed by his rabbis during synagogue services.
The name of Dr. Tom's old girlfriend is Amanda Mathieson. In real life, Amanda Mathieson is the name of the vice-president of finance for Temple Street Productions, the production company for this show.
