Knew a guy who was so fast that he could flip off the lights and get in bed before it got dark.

Infinity minus one is infinity. There are several levels of infinity, by the way. (We would all agree that the set of all integers is less in size than the set of all real numbers - Real numbers include all rational and irrational numbers - but yet both are infinite). From my old math training, it seems like I recall the levels of infinity being Aleph 0, Aleph 1, etc. If I get motivated, I'll see if I can find out any more from some old math books.
