In *Frasier*, Frasier mistakenly speaks Klingon at Freddy’s bar mitzvah. The incident occurs in the season-10 episode “Star Mitzvah,” when Frasier intends to deliver a speech in Hebrew but accidentally uses the fictional language associated with *Star Trek*.
Freddy is Frederick Crane, Frasier’s son with Lilith Sternin. Through his mother, Freddy is Jewish, so the bar mitzvah is an important family ceremony. Frasier’s attempt to honor the occasion becomes a comic disaster because he confuses Hebrew with Klingon, despite his confidence and elaborate preparation.
The joke depends on the contrast between Frasier’s intellectual self-image and his inability to handle a basic cultural task correctly. It also reflects the show’s recurring humor about the Crane family’s pretensions, misunderstandings, and competitive efforts to appear knowledgeable.
Klingon is not a real-world Jewish ceremonial language; it is a constructed language created for the *Star Trek* universe. The episode’s title, “Star Mitzvah,” combines the religious ceremony with the science-fiction reference. Freddy’s middle name, Gaylord, is also revealed in the episode.
