I forgot!
Perry is driving Lois, Clark, Jimmy, and maybe Jack (your choice of when this takes place) but the car gets stuck in a ditch. It's raining heavily. Clark volunteers to get out and push. Lightning strikes. No one knows that Clark is Superman. They may or may not know that Superman's powers can be copied. (Of course, it might be possible that Superman was flying overhead through the storm, perhaps coming to help them?) All they know is that suddenly all of them have powers...
