This is how they celebrated.

Just kidding. This is certainly not a celebration, but just a chance encounter between two aging action stars in a hospital.

The Governator explained on Twitter, “After all the action, stunts & physical abuse shooting The Expendables 2 and The Last Stand, it was time for a little tune up on my shoulder. Look who was coincidentally waiting in line behind me for his shoulder surgery. Now we're ready for another round of great times and action when we shoot The Tomb. #greattobeback

So, yeah. That is some heavy duty commitment to putting out films. I think we’re now all obligated to go see “The Expendables” sequel.
