Big Bang Theory Quote
Sheldon: (Ex nihilo) Leonard, I'm moving out.
Leonard: What do you mean, you're moving out? Why?
Sheldon: There doesn't have to be a reason.
Leonard: Yeah, there kinda does.
Sheldon: Not necessarily. This is a classic example of M?nchhausen's Trilemma: either the reason is predicated on a series of sub-reasons, leading to an infinite regression; or it tracks back to arbitrary axiomatic statements; or it's ultimately circular: i.e., I'm moving out because I'm moving out.
Leonard: I'm still confused.
Sheldon: Leonard, I don't see how I could have made it any simpler.
