Lousy Poetry and Bad Math

My kid brought a book home from school the other day: Naugty Little Monkeys by Jim Aylesworth. It makes me crazy. It's an alphabet book, where each letter equals a monkey. The first stanza refers to "all naughty twenty-six". BUT THERE ARE ONLY 25 MONKEYS. Because letter Z isn't a monkey, but is the ZOO where the 25 bad little monkeys go at the end of the book. Besides, the poetry is terrible and most of the stanzas don't scan right.
