When the child abductor posing as the "Ghost of Human Kindness" is arrested, he says "And I would've gotten away with it again if it weren't for you meddling policemen". This is a reference to the original "Scooby-Doo" TV series. At the end of nearly every episode, the masked villain is arrested by police and says "And I would have gotten away with it too, if it weren't for you meddling kids".
A man says "Say hello to my little friend" a quote from this film when he pulls out his missile launcher, just like in this film when he said it after pulling out a gun.
