Roz says that she had forgotten that Frederick was "half-Jewish". Although this is a common expression, according to Jewish Law, one cannot be half-Jewish. If one's mother is Jewish, they are Jewish; if she isn't, they are not.
In describing his "bar mitzvah" to Mrs. Moskowitz, Frasier mentions that his mohel (pronounced moyl) was present. Even if Frasier didn't have a Jewish wife and a son who was raised Jewish, it is highly unlikely that a man of his education wouldn't know what a mohel was.
Roz: I completely forgot Frederick is half-Jewish.
Frasier: Yes, between the Crane boy genes and Lilith's contribution, I'm not sure the NFL is holding its breath.
Helen: I guess you were bar mitzvahed here?
Frasier: Oh yes, yes of course. What a proud day that was. I can still remember reading from the Torah before the ... Rabbi... and the Cantor ... and the Mohel.
Helen: The Mohel?
Faye: The one who did your circumcision?
Frasier: Yes, yes. I just wanted to show him that there were no hard feelings.
Martin: I don't know how to be Jewish.
Niles: Well, just answer questions with a question.
Martin: Like what?
Niles: What, I have to explain everything?
Martin: Can't you give me an example?
Niles: What, I should give you an example?
Martin: Are you going to help me or not?
Niles: You're saying I'm not being helpful?

Fiddler on the Roof
When Niles is making a toast and trying to feign Judaism, he says, 'next year in Jerusalem', to which Frasier retorts, 'take it down a notch, Tevye!' "Next year in Jerusalem" and Tevye are references to Fiddler on the Roof, a musical about a family trying to maintain their Jewish culture and identity amid the changing times.
The title is an obvious play on the 1983 David Bowie/Tom Conti film "Merry Christmas Mr. Lawrence."
