Kearney's unnamed son is a possible son of Kearney Zzyzwicz.
He went to the small sandbox next to Moe's and he bullied Maggie, along other babies. When Homer learned it, he tried to rescue her, but Kearney's son started beating him. Maggie then punched him and saved Homer.
- He is referred to as "Kearney's Other Son" in The Simpsons: Tapped Out, thus confirming him as the offspring of Kearney.
