A shirtless man poses next to a man who is fully dressed in a t-shirt and cargo shorts who is pointing at the shirtless man's belly.
The Thin man points at the fat man's belly and makes a joke about him having no shirt on
The shirtless man does not necessarily have fat belly.  The man who is fully dressed is not necessarily thin.    Just because the thin man points at the shirtless man's belly does not mean that is making a joke about him not having a shirt on.
