Floyd Wetherton is a special commentator in Lois Griffin's boxing match with Deirdre Jackson in "Baby, You Knock Me Out". Floyd shows signs of brain damage and has very visible permanent disfigurement from his past experience as a boxer, giving nonsense answers to Tom Tucker's questions.
In the DVD cut of "Halloween on Spooner Street", Stewie stops to trick-or-treat at Floyd's house and gets a rambling monolog about turkey day and a lamp.
