Graph Jam

LOL, Caly. nice!

Not that good a grapher...but check out their companion sites Lolcats and Loldogs....bet Caly could post some of her kittehs on there and possibly make the main page!

I am a long time follower of the cat one, though I do it through another site (www.mycathatesyou.com) where there's a thread with lots of pics linked from icanhazcheezburger. Somehow the dogs just aren't as funny

follower of the site hell, my wife got me addicted, now i even have the icanhascheezburger widget.. lol.
