(Totally ripped out of context)
Achilles: ... Are you atheist, Mr. T? Or are you agnostic?
Tortoise: I don't think I'm agnostic. Maybe I'm meta-agnostic.
Achilles: Whaaat? I don't follow you at all.
Tortoise: Let's see... If I were meta-agnostic, I'd be confused over wheather I'm agnostic or not – but I'm not quite sure if I feel THAT way. hence I must be meta-meta-agnostic (I guess).
