In some states it is illegal to sing in a bathtub.
However nobody is really gonna enforce the laws about singing in a bathtub and thankfully so because many people sing in their bathtub and shower and would be getting fined or even arrested.
A lot of these dumb laws that exist are not enforced anymore even though they may still be on the law books.
According to the law you may not sing in the bathtub in the state of Pennsylvania.
VERMONT: In the city of Barre, residents must bathe on Saturday nights.
SOUTH CAROLINA: Horses may not be held in bathtubs.
The Bathtub Singing Prohibition Act of 1969 was passed by the Pennsylvania State Legislature in order to force talented singers out of such cloistered confines and make them perform nude in public instead.
The statute garnered widespread support among voters — except party-pooping Quakers who vehemently opposed the measure.
So go ahead and sign in the bathtub or shower if you want too because nothing will be done about it anyway.
