It reads, "Clark G is part of our Christmas display, please do not call 911".
The family put on the convincing decorations in a bid to win the neighborhood's holiday display contest.
This is the scene from National Lampoon's Christmas Vacation that the family was recreating with its decorations.
The Austin, Texas family dressed the dummy in similar clothes to those Clark Griswold wears in the movie, and positioned a ladder underneath him to match the scene where the dad hangs from the roof while trying to string up Christmas lights.
To complete the scene from the famous holiday movie, the family staged the dummy hanging from the roof and rigged a ladder underneath to make him look stuck.
'Can you reach it?' Norwood asked.
Austin police showed up and spoke to the nanny who was the only one home at the time.
The would-be hero, identified as Alfred Norwood Jr., was captured on camera trying to move a ladder to come to the rescue of the man, screaming for help and eventually calling 911 when the dangling person didn't respond. "Then I thought, 'Oh my God I hope he's not dead, lemme call 9-1-1'". "Whatever he had to do, he was going to save old Clark Griswold".
Since then, the family has added a sign to the bottom of the display that explains it's a Christmas decoration, for anyone who might be concerned.
Chris Heerlein, the man behind the decoration, and his sister-in-law Leah Wheless, tracked Mr Norwood down after the incident and gave him a gift card for his troubles.
