Boy 1 (explaining moral of story): Archers who steal ants' apples get bitten on the ankle.
Boy 2: Whaddya mean "ankle"? He was bitten on the toe!
Boy 1: Yeah, but "toe" doesn't begin with the letter 'A'!
-- Sesame Street: A Story About the Letter 'A'
Lately I find that I'm using "Yeah, but 'toe' doesn't begin with the letter 'A'!" to explain whenever I say something which isn't quite correct but sounds better than the more correct version would.
