Never one to fight or even advocate violence, Barry was in a bit of a pickle. He was being robbed by a rather nasty man.
Barry knew he had to act swiftly. He needed something to happen. Something that would stop the robber from being physically capable of the robbery. Barry scrambled over his mind mountain of ideas.
Twist his arm causing some sort of ‘burn’?
Firmly wag his finger at the robber?
No, no, no. He had to hurt him somehow. But where?
Lightbulb moment: where it hurts!!!
