He is dressed in a navy T-shirt, jeans, a baseball cap and boots.
The second of the two men is facing away from his counterpart and looks as though he was about to take a step forward.

Alternatively, it could also be summarised he is about to light-heartedly smack his colleague on the bottom.
Alas, the true story of what is going on may never be known.
