Carl Wheezer
A glasses-wearing boy with very low intelligence and one of Jimmy’s best friends, Carl is characterized by obsessions with llamas (which is a running gag throughout the series), and having a crush on Jimmy's mom, Judy Neutron. His unhealthy love for llamas stemmed when his parents inflated their cable lineups with a show within a show entitled Llama Boy the Superhero. From that point onwards, he goes to drastic measures to emulate them going far enough to a fan club nicknamed the Llama Love Society which is likely invented by himself.
