Ah, yes, the old petabyte potty.
And if you have very quick reflexes, you can catch those mischievous bits barreling into the bit bucket, and pull them out and use them again (like you said), but you may find that they have been rearranged just a bit.
(For example, where you once had a zero you might now have a one, and vice-versa.)
Two can be a compliment...Not to speak of the Little Indians...
