Looks like David Harbour is just as reliable as his 'Stranger Things' character, Chief Jim Hopper. After receiving a bizarre request on Twitter, the actor came through on his promise and actually officiated a fan's wedding.

How did it start? In January of this year, Twitter user @ErickaElizabth took to social media to ask, "What would it take to get @DavidKHarbour to be the Officiant at my wedding in September?!"

After posting, the internet worked it's magic and the tweet went absolutely viral. It got Harbour's attention and he promptly responded with his terms.

The actor wrote, "125k retweets. Provided date works with s3 shooting schedule, I will get ordained and perform ceremony. I get to read an esteemed love letter of my choosing, and after the cake is officially cut, I get the very first piece. #allthecakes."

Seems reasonable. Though most probably forgot about the tweet and the wedding, Harbour surely didn't and actually officiated the wedding—in full 'Stranger Things' costume.

Harbour shared a photo of the wedding party, writing, "Hey internet. I know it’s been awhile. I retreated. Needed some space. You probably get it. But I’ve been thinking about ya in the interim. And all your retweets. And so me and some fun folks in Springfield, Illinois made good on our promise we made all those months ago."
