Just a day after National Sibling Day flooded your Facebook feed with happy family photos, three brothers decided to celebrate their sister in a different way.

After their younger sister Millicent had her wisdom teeth removed, brothers Cabot, Hudson and Barrett Phillips convinced her that a zombie outbreak had hit their city. And, of course, they captured it all on video.

"The typical wisdom teeth videos are funny but we wanted to do something a little different, and thought the zombie aspect might be a fun twist," brother and instigator Cabot Phillips says. "We just didn't anticipate how expressive she would be, and how many one-liners she'd produce — even when terrified and in a drug-induced state."

They even staged a Center for Disease Control warning over the radio that "State and local officials have reported cases of high fever, nausea, death and even cannibalism."

"A garden hoe isn't what we want," Millicent asks at one point, exasperated. "We have guns, why are you putting garden equipment in the car?"

The highlight of the clip? When her brother breaks it to her that they can only take one pet — the cat or the dog — with them to Mexico, where, apparently, they will be safe from zombies. Her livid response? "The cat, you idiot!"

From there, it only gets better.

Phillips says a ton of people are commenting on the video saying what a great companion Millicent would be in a zombie apocalypse.

"She's no pushover and does her fair share of pranking her older brothers so she understood that we couldn't pass up an opportunity like this," Phillips said. "She took it in stride and just wanted to sleep once she realized that she wasn't going to be eaten by any zombies."

Wonder what Millicent has in store for her brothers next.
