Corrected entry: When Cartman goes to see Mephisto to ask him to make him a friend, Mephisto tells him that genetic engineering has not yet advanced to the stage where he can just make people. But in "An Elephant Makes Loves To A Pig", Mephisto easily made a giant clone of Stan.
Corrected entry: When Cartman's mom tells him that the Tooth Fairy is not real, Cartman says "I guess you're going to tell me that there is no Santa Claus, Jesus or the Easter Bunny", but Cartman knows that Jesus definitely exists because he went on his show in "The Mexican Staring Frog of Southern Sri Lanka".
Corrected entry: After Cartman's mom tells him he has twenty minutes to finish his play, Cartman says "Did Tim Rice's mom give him twenty minutes to write the lyrics to 'Phantom of the Opera?'" Tim Rice did not write the lyrics to "Phantom of the Opera," Charles Hart did. This was not a deliberate mistake or a comment derived from Cartman's stupidity, as musical theatre is too obscure of a topic for fans to laugh at when Cartman screws up its information.
