In ' Law And Disorder', Carl stalls for time by suggesting a therapeutic role-playing session between he and the mall burglar where he poorly sings as cabaret singer Billie Holiday. In ' Carl Be Not Proud', Carl makes Johnny play the role of Biff Proton while he plays Trip McCoy, dressing in full costume. He also knows a lot about nature, such as plants, wildlife, recycling, etc.Ĭarl is a huge fan of role-playing. Carl's other interests include history, mythology, and various cultures. His main interests are science, sci-fi (especially Trip McCoy: Galaxy Boy), and bugs. He is often over-enthusiastic, talking a lot and clapping his hands or exclaiming words such as 'Yay!' and 'Okay!' when excited. This resulted in him becoming more average-looking with rounder features.Ĭarl is intelligent, inventive, eccentric, timid, and friendly.
