If "Stranger Things" fans win, too.

When the list of nominees came earlier this week, Harbour and his co-stars were understandably excited to see him nominated in the best supporting actor category. He was the only one of the bunch to be nominated individually, but that didn't put a damper on their enthusiasm. After Harbour shared his excitement in an Instagram post, some of his co-stars quickly commented with their congratulations.

Joe Keery took it a step further. He commented as well, saying he'd let the show's creators, brothers Matt and Ross Duffer, shave his head if Harbour won, as EW reports. Frankly, they probably wouldn't want to given how his hair has played into the show, but the idea immediately set off alarm bells for many fans who shuddered at the idea of Keery's character, Steve, losing his trademark locks.

Fortunately, Harbour himself is planning a less extreme celebration if his name is called. He promised a fan on Twitter that he'd do the dance he did as Hopper to celebrate.

The dance is so popular that his co-star Millie Bobby Brown even referenced it when she congratulated him on his nomination.

And she had even more congratulations to share, as did their co-stars.

The "Stranger Things" cast knows how to celebrate one another -- and they may have a lot more to celebrate come January. The Golden Globes are set for Jan. 7 at 5 p.m. PT.
