Mr. Zzyzwicz is the father of Kearney. He looks similar to his son and grandson, except for his more rude appearance, his beard and his cigar.
He, along with Mr. Jones and Mr. Starbeam, beat up Homer at Moe's Tavern when he asked them about their sons giving Bart his belt back in Moe's Tavern. He was mentioned in "Lisa the Drama Queen" that he had a stroke at one point. In "The Fat and the Furriest", Kearney mentions that he is afraid of paying child support. In "O Brother, Where Bart Thou?" he and his ex-wife met mean the prison and the insane asylum had their annual mixer, showing that he was probably in jail.
