Here's a few more:

In California, you cannot shoot animals from a moving vehicle, unless the target is a whale.

Several communities in the U.S. (California again, also Texas, Illinois, South Carolinia, and Georgia) ban trick-or-treaters from wearing masks unless they get written permission from the Sheriff (or Chief of Police).

In Burlingame, CA, spitting is illegal-unless it's on a baseball diamond.

Also in California, Sunshine is guaranteed to the masses (sounds like something Jerry Brown signed into law when he was Governor the last time around).

Northhampton, MA prohibits the detonation of nuclear devices. It doesn't prohibit their possession or transport, but you can't set them off within city limits.

Salem, MA, by law, appoints a "city witch."

Dayton, KY requires Christmas Carolers to obtain permits.

Several states prohibit women from driving while wearing housecoats.
