Mr. Pulman is the bespectacled, weary science teacher at Bob LaBrea High School on Dinosaurs. He debuted in the second season episode "Employee of the Month" (in which Bruce Lanoil performed the body). He would be used periodically throughout the run of the series, teaching courses on caveman dissection, becoming involved in the debate over "mating dance" education, and chairing the school science fair.
In his final appearance, in the fourth season episode "Scent of a Reptile," Charlene briefly suspects the teacher may be attracted to her scent. In reality, he was simply longing to quench his thirst with the water fountain behind her.
