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.
