The legality of stripping

I am so bad at web searches and I'm in a debate with someone about when stripping was illegal and when it became legal. Does anyone know of any good websites that would have that info for me?

Hope this helps: http://en.wikipedia.org/wiki/Striptease

it became legal when some lady somewhere needed extra cash
and some joker with extra cash,bumped into eachother,her top came off,his cash hit the floor...they stared at eachother for a second...and bingo...some one started playing
a harmonica...and it was on...hahahahahaha...

It's been legal for most of human history. It's only in the last century that western civilization decided to criminalize activities such as stripping, prostitution, drug usage, and other victimless crimes. We used to be more sensible.
