Trivia: "Child's Play" creator Don Mancini has no involvement in this remake, and has openly stated that he's against it, as the original movie series is still going. Several other key cast and crew members from the original series have also expressed their disapproval of the film.
Trivia: On Andy's bedroom wall is a poster of Poltergeist 3 which was released in 1988, the same year the original Child's Play was.
Trivia: The original "Child's Play/Chucky" film series is still in production at Universal (with a planned TV series in the works), as Universal had acquired the franchise rights after MGM released the original film. However, as MGM still technically owns the original film, they were allowed to remake it, so long as it included no references to any of the sequels, as the sequels belong to Universal. Various scenes and portions of the script had to be rewritten several times, as they were found to be too close to scenes from the Universal sequels.
Trivia: The film makes several references to E.T. The Extra Terrestrial (1982). Chucky has a glowing finger. Chucky runs through the corn like E.T. does. Chucky also learns from the TV, as does E.T.
Answer: I wouldn't read into it much more than just a joke: Chucky heard that joke earlier when the kids in the street were trying to make him do things for their cell phone cameras. So he just re-used it later as he often does in the movie.

It was a joke that some kid said when he had the Chucky doll.
