How about this for fuzzy math? (w/due credit to Dubya)
Buzz Lightyear's "To infinity ... and beyond!"
BTW, I am convinced that hardly anyone can grasp magnitudes of any units (e.g., dollars in national debt) when they exceed about a million, much less billions or trillions.
I have adapted the convention of eschewing such "numbers", opting instead to refer to a "thousand million" or "million million". Yes, I'm aware that the European units are different, but the concept is the same - even if the numbers are still not grasped completely, at least the MEGO* factor is diminished when compared to hearing the virtually incomprehensible words billion, trillion, etc.
