Get Ready for a Scooby-Doo / Supernatural Crossover!!

No, this is not the Onion. The Onion would suggest the Supernatural gang is taking over Mystery Incorporated or some such in a bid to boost ratings for the flailing kid's cartoon enterprise and make it grittier for modern audiences... WHICH IS PROBABLY HAPPENING RIGHT NOW IN THE PAGES OF DC COMICS!!! I won't read that comic. You can't make me. What's NOT a joke is that we are getting an animated adventure in an upcoming episode of Supernatural's 13th season.
