Dawson Casting: Ralph Macchio was 21 when the first film was made, playing a 17 year old. He was 26 playing an 18 year old in the third film. Not many people noticed thanks to Macchio's boyish good looks and high-pitched voice,note making this one of the few effective examples of the trope. Avoided in the reboot, as the kids are actual kids. Poked fun at in a 90's commercial for Brisk Iced Tea.
"Daniel-San": Kid? I'm 35.
