Even frustrated grammarians will giggle at the who's-on-first routine that begins with a donkey's excited announcement, "I yam a donkey " Unfortunately the donkey's audience happens to be a yam, and one who is particular about sloppy pronunciation and poor grammar. An escalating series of misunderstandings leaves the yam furious and the clueless donkey bewildered by the yam's growing (and amusing) frustration. The yam finally gets his point across, but regrettably, he's made the situation a little bit too clear . . . and the story ends with a dark and outrageously funny twist.
