David Harbour from 'Stranger Things' makes fan promise for 125K retweets. They nailed it.

Good guy David Harbour is back with his big promises.

The Stranger Things star has pledged to become ordained and preside over the wedding ceremony of Twitter user @ErickaElizabth, but only if he got 125,000 retweets.

With the wedding slated for September, there was a bit of time to spare.

Of course, the wedding date will have to work with the shooting schedule of Season 3 of Stranger Things.

Not only that, Harbour will get to read a love letter of his choosing and eat the first slice of cake. A fair trade, we say.

Back in October, @postydamaris asked Harbour how many retweets it would take for him to get a senior photo with her.

That request only took 25,000 retweets, albeit Harbour demanded he wear the school's sweatshirt and hold a trombone. And you bet it was fulfilled:

On Wednesday evening, Harbour's 125,000 retweet requirement was broken in under 24 hours. Impressive. "I'm making it seriously hard next time," he wrote.

We just can't wait for the photos.
