Mark Twain

No, "but HapKiDo, his name was Samuel Clemens", crap! It's called a pseudonym & I'm using it! This is probably one of my favorite quotes of all time:

"It is by the grace of God in our country that we have those three unspeakably precious things: Freedom of speech; Freedom of conscience; and the Prudence to never practice either of them". - Mark Twain
