First off, I think it is sad that I actually had to look up this word to make sure I knew it's true meaning.. or at least know it enough to make sure my illustration fit it. It's just not a word you hear very often anymore. Or at least I don't.
Anyway, when I did read the word in question my immediate thought was that credit card commercial where the dad is buying his daughter a bunny but while waiting on the credit card to go through the rabbits multiply so rapidly that there are bunnies everywhere! See here for the only link to the commercial I could find: http://www.youtube.com/watch?v=DhieUXAapz8
Then I kind of felt sympathy for all the mama bunnies out there. So that is what brought about this sketch.
