I'm always in the market for a "flesh-angled" blog, and so when I saw this link on Nowhere Girl's blogroll, I had to check it out. Actually, quite amusing. I'm not a fan of the belly, per se, but the facial expressions are what really sells it for me.
A friend of mine once wrote a VERY short play called "Rrrrrrrub My Neeeeeples" or something to that effect. Perhaps the next adventure in the saga could be "Touch My Belly."
As for my favorite (I haven't scrolled through them all... have to save some for later, you know), I think it's probably "Hate."
