I yam going to remember this one to read to my class when we start our first unit on grammar. It would be fun to show them the "Who's on first" video along with it. The book is fun because the donkey really doesn't get it despite the cranky yam's attempts to teach him how to speak properly. Language can be confusing and tricky and the book proves that if you are too much of a stickler, you might meet an early demise!
The ending reminded me of I Want My Hat Back by Jon Klassen
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.
