That would be a ridiculously large light -- at least half the size of a human torso, with a diameter to match -- mounted on what is, again, a skinny metal railing. This interpretation makes only very slightly more sense than the safety cone.

But let's just say that I'm wrong about that one detail and there really is an object nonsensically perched on that railing for some reason -- which is possible. Forget the "gut" then, and look at the size of the man's torso, legs, and head, all of which contribute to the silhouette and consistent proportions of a man with a large gut.

Enhance.

He isn't even musclebound or barrel-chested: all of his outlines round out about the middle. His cheeks fill out his face beneath the beard. He's fat. Even if he really is standing behind something, he is still fat.

So... if it's Bo', what's he doing here? If it's not Bo', then he might still be important: Counterintuitively, people who are just standing in a pose, quietly existing in the background and doing nothing, tend to be important characters -- while random bystanders tend to be doing something interesting to give a sense of life and purpose to the space.

If it's just an insignificant background dude who's not worth splitting hairs over though, then I kinda like Bloodfang's idea.

I'd argue "It's called foreshortening dude" ...

If you had argued that, I might have replied, "You realize that foreshortening is not going to have a very pronounced effect on two objects placed very few inches apart, way in the background of the stage, right? You can still do a fair size comparison here."

BUT... in light of recent developments, this line of investigation has been rendered more or less moot anyway.
