Quote from Niles in Merry Christmas, Mrs. Moskowitz
Niles: Wait, Frasier, is that for Helen? Frasier: Yes. Niles: What if she's expecting Jewish wine? Frasier: Gosh, I'm afraid I don't have any of that on hand. Niles: It's all right, it's easy enough. It's just like regular wine plus a little bit of this... [adds sugar] Try that. Frasier: It's dreadful. Niles: Perfect.
