Kelsey Hall posted a photo of her wearing this adorably ridiculous Christmas tree outfit, complete with an indifferent expression about donning such a cheery garment.
With the photo, she penned a vow to wear the tree to all of her classes for the rest of the semester if it hit a thousand retweets.
And, at the time of writing, Hall's original post hit over 24,000 RTs, so...yeah.
Hall wasn't all that excited about keeping her promise.
She was out to dinner when she realized she had to put up or shut up, and her friend caught a snap of her incredulous face.
Again, she really, really didn't want to go through with it.
But her adoring public egged her on...
...and Kelsey had no intention of ever backing out of the bet.
She ultimately pulled through, and there's plenty of on-campus evidence to prove it.
In an interview with BuzzFeed, Hall says that the first day of wearing the tree to class she felt "really embarrassed", so much so that she enlisted the help of her friends to walk with her.
She went on to say that walking around campus with an umbrella in the costume was no easy task.
As embarrassed as she was, she could at least hold her head up high, underneath that glowing star, knowing that she is a woman of her word.
Students were ecstatic at the prospect of seeing Hall rocking her Christmas class outfit in person.
And, in the true spirit of Christmas, she made it happen.
Ahh, the holidays.
