Willy Wonka is a fictional character in the 1964 Roald Dahl novel, Charlie and the Chocolate Factory, and the subsequent film adaptations.
In "I Never Met the Dead Man", he inquires to Peter Griffin as to whether he ate the Three Course Dinner chewing gum. Peter, now a blueberry, repeatedly denied this.
He was also parodied as Pawtucket Pat in "Wasted Talent".
Brian and Stewie watch an extended director's cut of the film in "The Boys in the Band" in which, during the climatic glass elevator scene, Wonka informs Charlie that he has to "work" for the factory. When Charlie hesitates, Grandpa Joe jumps in and tells him he has to do it because he refuses to get back in bed with the other three grandparents and even offers to do what Wonka suggests himself, although Wonka cuts him off, insisting that it must be a child.
