Do not transport Mr. Fusion Flux Capacitor while in the vicinity of a plutonium powered nuclear reactor; while traveling faster than 88mph; or during a lightning storm. If a malfunction in the time circuits should occur and you find yourself in an altered past, present, or future, you will need to alter your past self so as to prevent a paradox that may unravel the space time continuum and destroy the Universe (or perhaps only the Milky Way Galaxy)!
