What's a wig hat?

Early readers can be hilarious. I mean, remember "Hot at the Dam"?

So today I'm reading "The Haircut" with student M. Here's the gist:

Edwin, the kid, is so shaggy he looks like the dog. His parents decide to give him a haircut but they don't know what the hell they're doing. Edwin's hair is choppy and weird. He's nervous about going to school.

So instead of going to the barber to rectify the situation, Mom goes to the closet to get out her old "wig hat" which she apparently wore one winter as a child. The "wig hat" has fluffly blond hair sticking out from under a red beanie. As Edwin exclaims, "It almost looks like hair!" Edwin wears it with gusto, to the mall and riding bikes with friends. It's the perfect solution to the problem.

Guess what, Edwin: you look ridiculous. "Wig hats" in real life are called toupees, and you're not supposed to wear them.
