Trey Parker has stated that his favorite reaction from a celebrity who was spoofed on the show came from Jennifer Lopez. Prior to ridiculing her in this episode, Parker also appeared at the Oscar ceremony in the same kind of dress Lopez had worn at the Grammys. When he saw her at a party some time later, she simply pushed past him without saying a word.
Cartman steals part of his ventriloquist routine from Señor Wences.
In real life, Jennifer Lopez has been known to fire multiple employees and assistants for mentioning this episode or quoting the lyric "taco flavored kisses".
The sound and dialogue of Jennifer Lopez is directly inspired by Richard Libertini's performance as General Garcia in The In-Laws (1979).
The "'s all right, 's all right" quote that Cartman does, is based on ventriloquist Senor Wences (Wenceslao Moreno Centeno (April 17, 1896 - April 20, 1999) ).
