That was Ruby Sue?
The little girl with the snake that Eddie told to go inside and work on her typing? He said "She must have grew a whole foot since you last saw her" and the last time we saw her was Christmas Vacation, apparently Ruby Sue doesn't age at all cause shes still a kid. Even though Rusty, Audrey and everyone else is years older after Christmas Vacation and Ruby Sue still looks to be 8 years old.
Rusty was clearly like 12 or 13 in Christmas Vacation and around 18 or 19 in Vegas Vacation, yet Ruby Sue looks to be the exact same age still that she was in Christmas Vacation.
Thats what i love about these high school girls, i get older they stay the same age.
