Second Generation Pet Rock is USB-Powered, Still Does Nothing

Maybe I'm just not a good pet owner, but I never understood the original Pet Rock. Mine just sat there holding down papers on my desk and refused to eat. Looks like this USB-powered one doesn't do much either.

Like the tauntaun sleeping bag, the USB Pet Rock is another case of an April Fools Day joke turning into a real product. This is the joke video from earlier in the year:

You can order your own USB Pet Rock for $10 at ThinkGeek. Just don't ask me to tell you what to do with it. I still try to feed Fido without success. [ThinkGeek via OhGizmo!]
