On this day in pop culture history: ‘National Lampoon’s Christmas Vacation’ opened in theaters

26 years ago today, the Griswold family cemented their place in the pantheon Christmas movies.

The third installment of National Lampoon”s “Vacation” comedy series features plenty of holiday hijinks ensuing  – including a squirrel in the Christmas tree, a sled ride made dangerous by an experimental substance, and a bit of kidnapping – as Chevy Chase”s Clark Griswold tries to keep it all together in front of his siblings. 

Fun fact: “Christmas Vacation” was one of two Christmas movies released in 1989, the other being John Hancock”s “Prancer.” Johnny Galecki, a.k.a. Rusty Griswold (now better known as Leonard from “The Big Bang Theory”) appeared in both of these holiday movies.
