== Torture == 

 I'm very tempted to remove this entire section. It basically says, "The Romans tortured people by having goats lick their feet. But that was primarily about pain. In Medieval Europe and Colonial America, people were put in stocks as punishment. But that was primarily about humiliation." So, it's not very much about tickling. And, there are no sources to back it up. It seems to me like this section has more to do with speculation and fantasy than documented facts.
