10 Most Meta Moments In Supernatural

10. Paging Dr Kripke - In My Time Of Dying (S2E1)

The earliest meta moment in Supernatural is very blink-and-you-miss it. Really, it's more of an Easter egg for the eagle-eared viewer, but still worthy of a mention because of its cunning subtlety.

Season two's premiere sees Dean Winchester at Death's door following a nasty car crash at the hands of Azazel. (The yellow eyed demon, remember him? Simpler times.) While his brother and father await news of his condition, the tannoy call goes out, "Paging Dr. Kripke..."

As any long time fan of the show will know, this doctor shares a surname with the show's creator and the showrunner of the first five seasons, Eric Kripke. Now, it's doubtful that this universe's Eric Kripke went into medicine rather than the media, so it's unlikely to be like, actually Eric Kripke.

But as far as self-insertion goes, it's a nice, fun factoid. And maybe that bit of fun gave Kripke and co. a taste for the meta which flourished into the maniacal nonsense Supernatural would become so well known for. After all, it wouldn't be the last time a familiar name popped up. Bobby Singer, anyone?
