Did 'Supernatural' Stars Jared Padalecki and Jensen Ackles Just Star A Prank War with 'Arrow' And 'The Flash'?

Supernatural's Jared Padalecki and Jensen Ackles may be the stars of the longest running genre series in America, but they also want to add Official CW Pranksters to their resumes.

During a promotional photo shoot for The CW on Sunday, Padalecki posted a humorous picture of himself, his adorable little booty, and Ackles pretending to relieve themselves on Arrow star's parking lot nameplate all over social media.  The Facebook caption read, "These all-day photo shoots REALLY take it outta ya! Jensen Ackles and I had to "create" our own bathroom! Know what I mean, Stephen Amell?"

It also looks like the 6'4'' actor ripped the sign off the wall in order to take stage the picture.

Amell, who is friends with Padalecki, took the joke in stride, responding, "That's the best thing that has ever happened in my parking spot," via Facebook.

But it didn't end there.  Ackles led the next offensive in what could easily become a full-scale CW Civil Prank War on Monday.  He posted a video abusing The Flash set on Twitter with the caption reading, "Hangin on the #TheFlash set w/@jarpad .. Hey @grantgust how do u get any work done with all these rules? #NeedNaps."  Check it out below.

If you're a Supernatural fan, you already know that you can't take the Winchesters anywhere, and it looks like the same can be said for Jared and Jensen.
​
Shots fired, Amell and Grant Gustin.  Let's just hope both stars stay away from Supernatural's beloved Impala when they retaliate.
