late 80’s-“we didn’t see London, we didn’t see France, but lucky us, we saw Iggy’s underpants”!
That’s basically all I remember about this book in which a grade-school boy is continually harassed by a female classmate. (The above was one of the things she said to him)
Turns out it’s Sidney, and the book is “Satch and the Motormouth” by Karen Sommer.
