Beakman's World is an educational series starring Paul Zaloom as Beakman, a scientist with crazy hair who answers questions sent in by viewers and explains them in large and humorous manners. He is always assisted by a female assistant (Josie, Phoebe, or Liza) and his lab rat Lester(Mark Ritts) who is more of an "overgrown man in a rat suit" and is not very intelligent. Each episode also contains a "Beakman Challenge" where the viewer is challenged to do a task which seems impossible at first but is scientifically simple.
