You wouldn’t by any chance be thinking of any of the following, would you?
“William John Bender. Hulking, beetle-browed, German immigrant who was the “Old Man” of the notorious Bender family.”
“Ma Bender. No Christian name has ever been mentioned, found, or imagined; maybe just as well, for any flowery feminine nomenclature would have sat badly on Ma.”
“John Bender. Moronic son of William and Ma Bender who, in spite of his low IQ and lunatic laughter, played no small part in the family enterprise: murder, presumably with a robbery motive.”
“Kate Bender. Daughter of William and Ma Bender, and sister of the moronic John.”
