Sylvester Stallone Just Hilariously Trolled Arnold Schwarzenegger on Instagram

And now, Stallone is taking his Instagram game to the next level. He just shared a Photoshopped image of himself with Schwarzenegger, but something about this post is different...

For years people have thought Arnold was taller than me, now, THE TRUTH CAN BE TOLD ! A post shared by Sly Stallone (@officialslystallone) on Jul 31, 2019 at 7:33am PDT

That's right, Stallone photoshopped Schwarzenegger to look shorter than him. Like, a lot shorter. "For years people have thought Arnold was taller than me," he wrote in the caption, "now, THE TRUTH CAN BE TOLD!"

It's all in good fun, of course: Stallone and Schwarzenegger are great pals, with Stallone, 73, recently wishing his friend a happy 72nd birthday.

Will Schwarzenegger retaliate on his own Instagram page? Could this be the start to an ever-escalating conflict, we wonder? Maybe Sly and Arnie will take a page out of Ryan Reynolds and Hugh Jackman's book , and wage a troll war against each other that goes on for years and years. Or perhaps embark on a series of increasingly surreal, self-referential social media gags, like John Stamos and Nick Jonas .

Somewhere right now, Arnie is sitting in front of his laptop with a stogie, watching a YouTube tutorial on Photoshop. And we can't wait to see what he comes up with.
