Phoebe Cates indeed has the more memorable boob scene.
She decides that the best thing to do is enroll in a nearby high school when her parents away and to pretend she is a teenage boy.
The farcical scenes with Terry making quick changes from female to male with Sherilynn Fenn in one room and Leigh McCloskey in the other are amusing and well played.
Terry is a capable writer but her subject matter is boring, regardless of her gender.
Okay, maybe more the second reason than the first.
