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.
