I was walking through a top secret government building full of radioactive waste for some known but illogical reason, and as I was running away from security I knocked over one of the barrels containing the radioactive waste. At the same time a lamp from the ceiling above fell onto said radioactive waste, creating a radioactive-electric beam that struck me down, thus giving me my powers.
If this sounds like the plot for some B-action/horror movie, I reassure you that it is not.
