Oh god, not this again - another day, another revelation about the kids from Stranger Things making hidden appearances on our favourite TV shows without us realising.

Finn Wolfhard, who plays Mike, took to his Instagram to post a cheeky little #TBT picture of himself on the set of... SUPERNATURAL and our minds have just exploded.
