Cartoon by Ed Stein
Edit 12/1/09: Apparently the cartoon has been removed from comics.com. Or maybe it has moved. I don't really remember what the cartoon was though, so it might be hard for me to find it again. I guess you can just try and think of something really funny, pretend that this cartoon said that, and laugh. You're welcome.
Edit #2: OK, that was easier than I thought. Thanks to comics.com for being so organized.
