Funny Boy faces his biggest threat yet—a plaque attack! Funny Boy's super-powered sense of humor has saved the world from airsick aliens, bubble-brained barbers, and a chain of chitchatting cheeses. It's even won him the love of his life: Tupper Camembert. But this riddle-flinging superhero's work is far from over. When the president of the United States is summoned for a cleaning with Dr. Denny the dentist, he knows something is wrong—he doesn't even have an appointment! This is a job for Funny Boy, who must once again use every joke in his arsenal to destroy the evil dentist villain and his hygienist henchmen. But does Funny Boy know enough dentist jokes to save the planet from an invasion of plaque? This ebook features an illustrated biography of Dan Gutman including rare images from the author's personal collection. Funny Boy Meets the Dumbbell Dentist from Deimos (with Dangerous Dental Decay) is the 4th book in Funny Boy, but you may enjoy reading the series in any order.
