Joel is one of Gary's best friends. He's about 15 years old. Has yellow hair, eyebrows, and brown eyes. Him and Gary invite Christina, who is Gary's neighbor, Martin's daughter, and her friend, Rachel to Gary's house for a party. At the party, Joel sees Danielle crying saying all boys think about are boobs like hers. Joel tells her about what Megan said about boobs only being "mounds of fat". When Gary goes to check on Joel, he is seen drinking her breast milk. Joel claims to be intolerant of people, due to Joel having a hatred for his older brother Brian.
