A glipse of the Rooney behind

Has anyone noticed in one of the lockerroom scenes (where Mickey is sitting on a table in just a towel in profile to the camera facing right), that his towel slips and the side of his rear is exposed for just a second? The actor standing near him covers him back up very inconspiculously! Mickey, who is in the midst of dialogue, doesn't notice a thing. It's so sweet the way that other actor protects him. Look for it. By the way, I agree this is one of the Mick's best. He is so awesomely talented in everything he does. A national treasure.
