I've chosen only one silly law from each state that I thought was the silliest/funniest one. 

Alabama: Boogers may not be flicked into the wind.

Alaska: Moose may not be viewed from an airplane

Arizona: Hunting camels is prohibited.

Arkansas: A law provides that school teachers who bob their hair will not get a raise. 

California: No vehicle without a driver may exceed 60 miles per hour.

Colorado: Car dealers may not show cars on a Sunday.

Connecticut: It is unlawful to walk backwards after sunset. (in light of the snow storm that we just had, apparently  it is also illegal for CT light and power to get electricity back to the residents sooner than 1 week after the power went out.)

Delaware: It is illegal to fly over any body of water, unless one is carrying sufficient supplies of food and drink. 

Florida: You may not fart in a public place after 6 P.M. on Thursdays. 

Georgia: (a lot of you will love this one, especially those of you who are part of the "Why did the chicken cross the road club).... It is illegal for a chicken to cross the road. 

Hawaii: Coins are not allowed to be placed in one's ears. 

Idaho: Residents may not fish from a giraffe or camel's back.

Illinois: One may not pee in his neighbor's mouth. (Illinois has some great ones! It was hard to choose.)

Indiana: Baths may not be taken between the months of October and March.

Iowa: Horses are forbidden to eat fire hydrants.

Kansas: The state game rule prohibits the use of mules to hunt ducks. 

Kentucky: A woman may not buy a hat without her husband's permission.

Louisiana: It is illegal to rob a bank and then shoot at the bank teller with a water pistol.

Maine: To stroll down the street playing a violin is against the law. 

Maryland: It's illegal to take a lion to the movies. 

Massachusetts: All men must carry a rifle to church on Sunday.

Michigan: It is against the law to serenade your girlfriend. 

Minnesota: A person may not cross state lines with a duck atop his head. Citizens may not enter Wisconsin with a chicken on their head.

Mississippi: It is unlawful to shave in the center of main street. 

Missouri: Minors are not allowed to purchase cap pistols, however they may buy shotguns freely.

Montana: It is illegal to have a sheep in the cab of your truck without a chaperone. 

Nebraska: If a child burps during church, his parent may be arrested. 

Nevada: It's still "legal" to hang someone for shooting your dog on your property. 

New Hampshire: On Sundays citizens may not relieve themselves while looking up.

New Jersey: It is against the law for a man to knit during the fishing season. 

New Mexico: (This one should be nation wide) Idiots may not vote. 

New York: (NY also has some great ones! Once again it was hard to choose) A fine of $25 can be levied for flirting. This old law specifically prohibits men from turning around on any city street and looking "at a woman in that way." A second conviction for a crime of this magnitude calls for the violating male to be forced to wear a "pair of horse-blinders" wherever and whenever he goes outside for a stroll.

North Dakota: One may be jailed for wearing a hat while dancing, or even for wearing a hat to a function where dancing is taking place.

Oklahoma: Oklahoma will not tolerate anyone taking a bite out of another's hamburger.

Pennsylvanian: It it illegal to sleep on top of a refrigerator outdoors. (Apparently sleeping on top of one indoors is fine.)

South Dakota: No horses are allowed into Fountain Inn unless they are wearing pants.

Tennessee: It's illegal for frogs to croak after 11 PM.

Utah: Pharmacists may not sell gunpowder to cure headaches. 

Vermont: Women must obtain written permission from their husbands to wear false teeth. ( no need to even guess the reason for this) 

Virginia: No one may wash a mule on the sidewalk. 

Washington: A law to reduce crime states: "It is mandatory for a motorist with criminal intentions to stop at the city limits and telephone the chief of police as he is entering the town." 

West Virginia: Roadkill may be taken home for supper. 

Wisconsin: If one is thought of as offensive looking, it is illegal for him to be in public during the day. 

Wyoming: You may not take a picture of a rabbit from January to April without an official permit.
