49. Vacation (1983)
Memorable quote: “Why aren’t we flying? Because getting there is half the fun. You know that.”
Laugh factor: Sure, it’s easy to relate to the family car trip gone haywire. However, most travelers would likely have a limit to the madness. In this National Lampoon laugher, Chevy Chase and his clan must really want to make it to a fictional theme park to endure the massive obstacles that arise, one of which is of course Randy Quaid.
