Heh, heh. This was a good one. I won't spoil it. Here is the link.
It's easy to slap around the Dem's, but what about the other guys? I'll choose the giant tick for the phylum republica. It finds a warm, dark place and then quietly sucks up as much of someone else's lifeblood as possible. Finally, it becomes too fat and disgusting to be ignored any longer. Naturally, it is then removed and squashed. And although it's large and voracious for a tick, it still has a small brain, and no one can be sure if it's learned from the experience.
