Trivia: In the superhero segment, all five Griffins get similar powers to those of the X-men. Stewie's telekinesis is similar to Xavier/Jean Grey, Chris' fire powers are similar to Pyro, Lois' super strength is similar to Colossus, Brian's speed is similar to Quicksilver, and Meg's nails are a reference to Wolverine's claws.
