I love to see people who get all bunched up over the horrible "copyright violation" involved in using a kid that kind of looks like Calvin, but using him to pee on things.
Seriously, there's a large movement (or at least was) to shame people into not using that likeness.
Those people are as huge a joke as the ones that don't REALLY understand "Fair Use," but argue it to the death that hotlinking an image is a copyright violation.
That said....good choice of avatar, Ed! Am I being kill joyish enough?
