Even funnier considering this was an ad-lib by Brad Dourif. Doubles as a foreshadow of the character becoming deliberately Laughably Evil in the sequels.
When Karen threatens to throw Chucky into the fireplace, causing him to spring to life (note: this is before he officially became Laughably Evil).
"YOU STUPID BITCH! YOU FILTHY SLUT! I'LL TEACH YOU TO FUCK WITH ME!"
Andy tries to get Chucky to talk in front of everyone, resorting to shaking and hitting him. When Chucky respond with one of the doll's catchphrases ("Hi, I'm Chucky and I'm your friend till the end. Hi-de-ho! Ha, Ha, Ha!"), Andy angrily punched Chucky in the gut.
One in particular was when none of the kids knew who Bill Cullen was!
One child said a "yo-yo" was a "stupid person".
For "liar", a girl instantly said, "My brother's one!"
One boy said Johnny Carson was "old" and he had "a lot of wrinkles". Bill Cullen even agreed!
Any time a kid said the word they're describing, it got bleeped out and an "OOPS!" graphic was placed over the mouth. In one description, a boy said the word so many times that the camera operator had to remind him that he wasn't supposed to say it.
