What are you doing, Benny?

"Benny's little brother is really good at a lot of things--making potions and paper airplanes, building forts, putting on puppet shows, even petting the neighbor's cat (he has a special way of scratching her just behind the ears). But whenever he tries to join in Benny's activities, all Benny ever says is "No." Maybe his little brother can watch him do cool stuff, if he's lucky. What is a little fox to do, except give Benny a taste of his own medicine?"--Amazon.com.
