You have two lightbulbs with exposed wiring that are blinding when you turn them on. You have the light switch nearby too, a fishing pole, and a knife. There's a small tank of fish and you want to kill them all as fast as you can. How do you do it with only the resources available to you? You can't use anything I didn't list and you don't have to use everything.
