This is a mashup of the Magnum P.I. opening starring Hopper from Stranger Things. Obviously if you're ever seen the show, it's a near-perfect fit, kinda like-- "Let me guess, your penis in a subway tunnel." Only if I wasn't in the mood.
Keep going for the video, complete with theme song.
Thanks to Stephanie B, who agrees Thomas Magnum and Jim Hopper working together would be an unstoppable force of mustache and handsome.
