It might have a sombrero.

Yes, that's right - wait, no it isn't. That isn't ever an appropriate answer to "how"! You'll have to ask another extrauniversal force for an opinion.

You got it back because that would be, if not a bad idea, at least not a good one. How is irrelevant, but needless to say it involved a DeLorean.

You already know the exact reason why you did this and had no need to consult extrauniversal forces to learn that. What you're concerned with is how, because you can't remember and find that very disconcerting. The DeLorean does sound familiar, though.

Hypothetically, if a DeLorean were modified for temporal and cross-dimensional travel, you could use it to return to a time when the bad idea ray existed and take it for your own use. You could also use it for travel to Hell in order to point it at this demon. This is a perfectly sensible hypothesis, though it would be more compelling if you had an actual DeLorean nearby.

Regardless, if this is true you must return the bad idea ray to its original time period once your objective is complete. Otherwise you might cause a temporal paradox of some sort. That means you will have to locate this hypothetical DeLorean or some other means of time travel and a way out of Hell. Where in Hell are you going to do that?
