I'm glad the State of California is so smart

I found this sticker on a car while we were at Disneyland. Being myself, I had to take a picture of it. My dad said he saw a similar sticker affixed to Disneyland (yes, Disneyland itself) but we couldn't find it later to take a picture of it.

Whilst trying to find information on this warning that Disneyland could cause cancer and reproductive harm, I stumbled across a few choice related items:

MSDS for water
An MSDS, or Material Safety Data Sheet, tells you what is hazardous about a particular substance. In this case, it's for water.
An interesting discussion on this. A mouse had one of these warnings affixed to it, saying that you should wash your hands after touching the mouse.

I won't add any more; it's already quite enough.
