'Stranger Things' Star David Harbour to Officiate Fan's Wedding After Twitter Challenge

'Stranger Things' star appeared to have underestimated the difficulty of getting 125K retweets.

David Harbour needs to make his Twitter challenges a little harder.

Less than 24 hours after a Stranger Things fan asked how many retweets it would take for him to officiate her wedding, a fan named Ericka had more than enough to get Harbour to commit -- so long as he gets the first piece of cake.

The Twitter exchange played out in a perfect, bite-sized, three-act play.

"What would it take to get @DavidKHarbour to be the Officiant at my wedding in September?!" Erica asked on Twitter.

"125k retweets," Harbour responded in kind. "Provided date works with s3 [Stranger Things] 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"

And finally, Act III:

"Dammit.  Not even 24hours," Harbour tweeted.  "You’re kidding me. @ErickaElizabth DM me please to get the ball rolling."

Harbour, 42, and fellow cast members are basking in the glow of widespread acclaim for the Netflix series' second season, which was released in October. Netflix has already renewed the series for a third season, which is expected to begin filming this spring and continue the bizarre tale of the fictional town of Hawkins, Indiana, in the 1980s. Harbour plays Jim Hopper, the police chief of Hawkins' police department.

For now, it appears Harbour may have learned his lesson from this particular exchange.

"I’m making it seriously hard next time," he added. "Internet, this is not over between us..."
