Gavin is a spoiled kid about the same age as Bart.
Gavin's only known relatives are his sister Caitlin and his mother, who spoils him. For example, after she's already bought Gavin several other video games, she gives him two Bonestorm video games. Gavin insists on getting two because he doesn't want to share with Caitlin. Bart, seeing the exchange, says that Gavin must be "the happiest kid in the world."
Gavin is later seen with his mother buying breakfast cereal and expressing the desire to live with one of his fathers.
