A Texas family's Christmas display ended up the subject of a 911 call when a passerby thought a mannequin was in danger.

The Heerlein family said their Austin display, inspired by the film National Lampoon's Christmas Vacation, includes a dummy version of Chevy Chase's character, Clark Griswold, hanging from the roof in tribute to famous scene from the Christmas classic.

The family said they bought the dummy online and decked it out in a Chevy Chase mask and clothes like those the actor wore in the film.

A security camera outside the home was recording when a concerned passerby mistook the dummy for a real person in danger.

"Oh mister, please hold on!" the man says while trying to move a ladder that serves as part of the display.

The man was unable to reach the dummy, so he called 911 to report a person in danger.

Austin police quickly determined the person in danger was actually a dummy.

The Heerleins have now added a sign to their display: "Clark G is part of our Christmas display please do not call 911."
