Corrected entry: The lines "In France every Frenchman knows his language from A to Z; the French don't care what they do, actually, as long as they pronounce it properly" do not rhyme as "Z" is only called "zee" in the U.S. (Alan Jay Lerner, the lyricist, was of course American.)

Correction: The line about the French is an observational aside, completely out of the rhythm of the song, as such it doesn't matter whether it rhymes or not (since it doesn't scan anyway).
The lyric is "knows his language from A to Zed."
