Kearney Zzyzwicz is one of the school bullies and is a part of Nelson's gang, but is way too old to still be in school. Kearney is in his twenties and even has a son named Little Kearny and a wife he's referred to. Maybe one day he'll graduate elementary school.
Lisa: You punks are about to get a taste of your own medicine, this is my brother and he knows karate!
Jimbo: Oh, we're real scared!
Kearney: Please don't hurt us Bart!
Dolph: What are you gonna do? Throw your diapers at us? Haha!
Lisa: Yeah just keep laughing, you know it makes him madder! Come on Bart, start em off with the touch of death, and go from there!
Bart: I think they've learned their lesson already
Jimbo: No! We wanna see the touch of death!
Jimbo: No matter how dead their relationship seems, all parents eventually commit the heinous acting of love.
Kearney: Mine do it once a year on the magical day when the prison and the insane asylum have their annual mixer.
