I'm particularly fond of UZC: The Unofficial Zeo Comic. One of the folks at the Pokemon message board I frequent (and mod) does it with characters loosely based off of folks there. I'm a snake.

Then there's my bro's comic site,
www.itbcomics.com (Rating: G, sometimes PG for comic violence).
And then there's my lowly site,
www.billfredindustries.com (Rating: NC-17 for too much pent-up rage vented. Kidding...PG.)
