(CNN) "Stranger Things" star David Harbour is willing to do a few favors for his followers.

The actor responded to a fan's tweeted request that he officiate her wedding with a challenge.

"125k retweets. Provided date works with s3 shooting schedule, I will get ordained and perform ceremony," Harbour replied in a tweet on Tuesday. "I get to read an esteemed love letter of my choosing, and after the cake is officially cut, I get the very first piece."
