A male character decides to test the effectiveness of acne cream by applying it to only half of his face for a few weeks. Near the end of his trial, he decides to include some of his similarly disfigured friends in the experiment. To be extra-super-scientific about it he decides to randomly (through coin toss) choose who uses each type of cream. As he flips the coin, Batman yells “You!” and punches him in the face.
The reason batman did that is because the male character had acne on half of his face and was flipping a coin, so he looked like the villain Two-Face.
Don’t worry, calm down, there is still a graph in this comic strip. It’s right there in the first panel for some reason.
