Creative graffiti of your pal's daemon. Here's how it works: go over to the Golden Compass website and get yourself a daemon. Slap a link or paste in their java flashy thing to your page and get people to start fucking with the sliders until you end up with a platypus.
This game meme has the added benefit of promoting a movie that the Religious Right is frothing mad about, despite the fact that the producers have already caved to those fucking lunatics. I wonder if the Religious Right got so worked up about Star Trek 5?
One final note: I don't know if you can actually get a platypus for a daemon, but if someone does, they win.
