Two circles sit on a white shirt, and only one of them is real. At the upper left, a dashed outline marks where a ball would be if it had stayed on the ledge. At the lower right, a solid white ball rests on the flat. Between them, a curved ramp descends. Above it all, in white capitals: I HAD POTENTIAL. The I Had Potential shirt is a physics diagram that has already resolved its own experiment, and the resolution is not flattering.
What interests me is not the joke, which is old and serviceable, but the drafting. The dashed circle is the ghost of the ball at its starting position—the counterfactual, the version of the object that never rolled. The solid ball is the actual. The ramp is curved, not a straight diagonal, which matters: a straight line would read as a graph, an abstract decline. A curve reads as a track, a physical path with a beginning and an end. The shirt is not saying potential decreased. It is saying potential was converted, and the conversion left a residue at the bottom.
That is the correct physics, roughly. A ball at the top of a ramp has gravitational potential energy; at the bottom, that energy has become kinetic, then heat, then nothing you can point to. The diagram is a closed system. Nothing was lost; something was spent. The dashed circle is not a promise. It is a ledger entry for a quantity that has already been transferred out.
Most slogan shirts treat potential as a moral category—you had it, you wasted it, feel bad. This one treats it as a measurable one. The dashed line is the giveaway. A dashed line in a technical drawing means hidden, removed, or projected. It is the convention for the thing that is not there but must be accounted for. Whoever drew this knew that the joke only works if the absence is drawn as carefully as the presence. The empty circle is the most honest mark on the garment.
I keep thinking about the flat ledge at the lower right. The ball is not falling. It is not mid-roll. It has stopped, and the ramp behind it curves up and away. The composition is stable, almost restful. This is not a shirt about failure as drama. It is a shirt about failure as equilibrium. The system has reached its lowest energy state, and the lowest energy state is a person standing still in a white t-shirt.
There is a version of this design that would be cruel—the ball at the bottom, the dashed circle at the top, and a caption that sneers. The capitals here are even and uninflected. I HAD POTENTIAL is a statement of fact, past tense, no exclamation point. The sarcasm is in the gap between the drawing and the sentence, not in the lettering. The shirt does not tell you how to feel about the ball. It just shows you where it is.
What the diagram asks of the wearer is a small act of self-description. You are not claiming you were a genius. You are claiming you were a ball on a ledge, and now you are a ball on a floor, and the distance between those two positions is the whole of a life. That is a modest claim, and a precise one. It is also, in its way, an invitation: the dashed circle is still there, still drawn, still part of the system. The potential did not vanish. It was converted. The shirt is a receipt.
