He reveals that he shot a special beam at the flash using a fake camera and he is anxious to see the results of the beam. The next day Flash finds himself at a The Coronet Shop where a jewelry robbery is taking place. Flash has no difficulty subduing the criminals, but he then notices that the crowd of witnesses is looking at him in horror. Flash realizes that he has a pounding headache and when he feels the top of his head, he finds that it has expanded to the size of a watermelon. Flash notifies his wife of his situation and tells her that he is heading to his lab to see if he can cure himself. He feverishly conducts experiments while dealing with his agonizing headache. At one point Flash steps outside to clear his head and finds himself confronted by the Trickster.

He drags the flash back to his lair and reveals that he wants to see the Flash's head explode as it keeps expanding. He reveals that he conducted experiments on his pet bird but Flash notices that the bird's head is normal and he deduces that the Trickster has some way of returning his condition back to normal. The Trickster then blows up a balloon to demonstrate what will happen to his head. The balloon bursts and Flash springs into action and attacks the Trickster. As he fights the villain, Flash realizes that he is not longer suffering from his pounding headache.
