this picture will never not be funny
just the absurdity of donald duck putting out that statement (which even makes some sense and fits donald’s overall depressed mood) and mickey mouse being the sly one and contradicting donald, coming out with the upper hand from the argument, is just so amusing.
I think it is also about the terms of the debate and definitions of self. For me the absurdity is to propose invisible essences that transcend physical reality. My body is my self and I kind of own or rent the material that makes me work. The processes are physical as well, but they are mine too. I freely make decisions all the time, all by myself. There is no other self worth talking about.
