This was supposedly a total coincidence, but I'm not sure I buy it . . .

Arnold Schwarzenegger went into the hospital for shoulder surgery recently, and he ended up in a bed next to Sylvester Stallone - who also just happened to be having shoulder surgery at the same time.

Arnold posted a subtly homoerotic photo of the two of them, side-by-side in their beds, and shirtless.

And he said, "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 '."
