There's a Boy in the Girls' Bathroom is a 1987 juvenile fiction book from the author Louis Sachar, about a fifth-grade bully named Bradley whose behavior improves after intervention from a school counselor.

[1] The title comes from a point when a character, Jeff, is horribly embarrassed after accidentally entering the girls' bathroom while trying to go to the school counselor's office when a teacher gives him the wrong directions.

In his school, he sits at the back of the class, last seat, last row, and never pays any attention, preferring to scribble, cut up pieces of paper, or partake in other mindless tasks which keep his mind off the lesson.

Bradley refuses to come quietly, and his conflicting emotions with Carla and other people induce strife among his fellow schoolmates.

A subplot of the book involves Jeff and a girl named Colleen Verigold (described as having "red hair and a freckled face"), who seem to have crushes on each other.

Later, Carla tells Jeff and Colleen that Zen Buddhist monks are required to say "Hi" to each other when they meet (as stated in J. D. Salinger's book Raise High the Roof Beam, Carpenters and Seymour: An Introduction).

They include a brass lion he found in the garbage, an ivory donkey his parents brought back from Mexico, two owls that were once used as salt and pepper shakers, a glass unicorn with its horn broken, a family of cocker spaniels on an ashtray, a kangaroo, a fox, a raccoon, an elephant, a wooden hippopotamus, and other china animals too chipped to identify.
