For Walking Dead fans, Jeffrey Dean Morgan will always known as Negan, the vicious bat-slinger. But for Supernatural fans, he’s John Winchester, father of Sam and Dean. And yet, there are some similarities between the two characters: They both love leather jackets, and they both enjoy killing non-humans.

The crossover between worlds is something Morgan and Supernatural star Jensen Ackles have had fun with in the past, but last week’s Supernatural took things to a new level. The opening shot of Sam and Dean at the bunker featured Dean holding none other than Lucille, Negan’s bat, as Dean declared, “Dad loved this thing.”

Now if only the Impala would show up on The Walking Dead. (Although, maybe we should hope the crossover action ends here, because the last thing Sam and Dean needs is zombies.)
