The Griswold family adventures became a cult classic beginning in the ‘80s with the first "National Lampoon’s Vacation" movie.

Chevy Chase, Christie Brinkley and Beverly D'Angelo reunited almost 40 years after the release of the first film as they enjoyed some downtime before hitting a comic con in Pennysylvania.

"These Three Amigos are going to need a Christmas Vacation after @steelcitycomiccon," Brinkley captioned a photo with her friends on Instagram. "I just love you two."

The trio were dressed in their most festive holiday attire and wore matching Christmas sweaters with embroidered reindeers and snowflakes.

"The Three Amigos," Chase echoed on his own account. Juliette Lewis, who played their daughter in the 1989 "National Lampoon's Christmas Vacation," responded back with a host of emojis.

D'Angelo was just as excited about seeing her friends and wrote, "HIGH SCHOOL REUNION."

"Threes never a crowd with this crew," Chase commented.
