matter/anti-matter?

Today's quote from the boy: " Mom, would you bet that 697 plus 55 copies of me can lift the world?"

Any guesses on what I replied?

BTW, I am not the mistress of my domain here. Turns out that a flaw in drupal---don't ask, I'm just repeating what the 'savant said---caused me to erase all the comments ever made on this blog when I was trying to clean out my approval queue.(where comments from unregistered users go to wait for approval AKA the spam filter) And do you know that the 'savant had the nerve to say it was my fault until he did a little research? (in lieu of an apology on bended knee, I'll accept your putting reloading them in the #1 spot on your to-do list, dear) Yes, like any good computer savant, he had made a back-up cache of the blog. However, he did this in Aug. so any comments since then are gone forever. So, if you don't see your previously posted comment, it's a technical glich rather than an editorial slight.
