Hibbert while he performed a sonogram on Marge when she was pregnant with him, and moments after being born, he set Homer's tie on fire Marge saying that he could not have done it on purpose because he was only ten minutes old . Also adding that he is very much like Bart, as like his son, he is greatly misunderstood and insecure about his place in the family. Instead of outright refusing the challenge, Bart instead tries to intentionally miss the bird. He also has been nicknamed "Cosmo", after discovering a comet in "Bart's Comet". Focusing his energy allowed Bart's intellectual potential to reach its maximum, even to the point where he was capable of tutoring a Navajo boy. Bart's first words were " Ay Caramba ". Homer has missed the show, and the endless debate about all that malarkey those jokes that everyone stopped making two years ago that were mentioned in the main post. However, he has put limits on the trouble he can cause; he won't lower himself as to stealing the school textbooks like Lisa did while he was the hall monitor. Despite his behavior, Bart is also extremely good at science, art and even sports like skateboarding. Appearance Bart has yellow skin and blond spiky hair that matches the color of his skin similar to his sisters , sports a slightly fat belly, and, like the other characters of The Simpsons, has big black pupils with no colored irises for eyes. In " The Crepes of Wrath " while on an exchange trip to France, Bart managed to learn French without even realizing it simply by being in the vicinity of Ugolin and Cesar , two men who regularly spoke French. Marge and Homer became concerned for his erratic behavior and tried to take him off the drug, but the prospect of losing his intellectual edge over his enemies causes Bart to go berserk and sneak into Fort Fragg to steal one of its tanks. Unfortunately, Bart doesn't compensate for a crooked sight, and he accidentally kills the bird. After blazing a path of destruction through the town, Bart uses the tank's cannon to shoot down an MLB satellite, thereby actually proving his suspicions to be correct. Even though at other times, Bart is shown bonding with his father, such as through coin collecting or selling grease.
