Scooby-Doo references and Easter eggs in SUPERNATURAL
"Scoobynatural", the crossover between the hit CW series "Supernatural" and Scooby-Doo, aired on this day 4 years ago. But it was far from the first time Scooby and the gang were mentioned. Check out this compilation of Scooby-Doo references and Easter eggs throughout the 15-season run of "Supernatural".
(Note 1: I have not included the actual "Scoobynatural" crossover whatsoever, because the whole episode is filled with references.
Note 2: I apologize in advance, because some of the clips are too long, just for the audience to have some context. Thank you to everyone who watches it all the way through!)
