'National Lampoon's Vacation'
There are a few high-brow flicks on this list, but "National Lampoon's Vacation" isn't one of them. That's OK, though, as this nearly 30-year-old film will still leave you laughing. It features Chevy Chase as Clark Griswold, a father who longs to spend more time with his family. He decides to take everyone on a cross-country road trip to visit the fictional Wally World theme park, but between lost credit cards, a vicious dog and a deceased aunt, nothing goes as planned. Chase reprises the role in several sequels, though this initial outing is the Griswolds' funniest vacation.
