High school student Damaris Fregoso is a big fan of Stranger Things, so she came up with an interesting request.

She tweeted to the show’s David Harbour, “how many retweets for you take my senior photos with me?” Being the cool guy that he is, Harbour actually replied back, though he had conditions: “25k.  And I get to wear the school sweatshirt and hold a trombone.”

30,000 retweets later, and Harbour made Fregoso’s dream a reality.

And, as you can see from the photos below, Harbour was not kidding about the trombone.
