that happened, you told me the whole story. you were standing on your toilet and you were hanging a clock, and you fell, and you hit your head on the sink, and that's when you came up with the idea for the flux capacitor, which makes time travel possible.

Doc: It works, ha ha ha ha, it works. I finally invent something that
