I love Mark Tatulli's comic strip Lio, which features a kooky little kid. To give you an idea of the off-kilter tone of the comic strip, Lio sleeps with a stuffed bunny that has vampire fangs. Hee. This kid is right up my alley.
Plus, he seems to spend a lot of time in libraries. Check out this one from about ten days ago. It entertained me no end.
