Common Sense Note
Parents need to know that National Lampoon's Vacation is a 1983 comedy filled with inappropriate behavior from both adults and tweens. There is frequent profanity, including a tirade filled with "f--k," brief female nudity (breasts), sexual innuendo, an incest joke, and a dog killed after being left leashed to the back bumper of a station wagon after driving down the highway. Though drug use and sex are never seen, they're very frequently implied and are generally the butts of jokes. The father comes close to cheating on his wife but doesn't succeed and realizes that he loves his wife. As with every other social taboo this film encounters, the father's almost-cheating is treated as a joke, as he is rather inept at it. Two tween boys look at pornographic magazines and talk about masturbation. Two tween girls look at a shoebox one of them keeps that's filled with marijuana; she later gives five joints to the girl on the road trip, who acts giggly and high in later scenes. An elderly woman dies on a road trip and is left in the rain on a lawn chair in the backyard of a relative who isn't home. There's also gunplay and use of the word "retard."
