"I don;t wanna grow up 'cause if I did, I wouldn't be a Toys 'R Us kid." How cute. Toys R Us enables Peter Pan syndrome among the youth of America. Also, what an awesomely simple jingle. The test fo a jingle is, can kids sing it.
In 1970, Remco made the Baby Laugh a Lot, a 16" tall doll with a plastic head and soft plush body that would not stop laughing (if you pushed the button). The wide open mouth had teeth. TEETH. Very creepy.
