Down the Drain! by Robert Munsch

Robert Munsch's hilarious take on bathtime is a long overdue tribute to the kids who dread taking them―and the poor parents who dread giving them! Adam is covered in dirt. His hands are dirty. His face is dirty. And his feet are dirty. "Adam, you need a bath!" his father yells. But Adam doesn't like baths. All that soap in his eyes, soap in his ears, and soap in his mouth! He doesn't like them one bit. So while his little sister, his dog, and his cat are laughing, Adam's father outsmarts him and pops him in the tub. Little does Dad know that Adam has a few tricks of his own...and once he's in the tub, in control of the tap AND the plug, the mayhem will begin!
