Funny story, when I was young I was sitting at a poker table with a group of guys I did not know. Any ways early on I am heads up with this guy and end up calling all in and winning. I then tell him I knew he was bluffing because he was so nervous, I literally said " you are shaking like a leaf, dead give away!". He then raises both his arms from under the rail and they are shaking uncontrollably. He says " I have early on set Parkinson's asshole". I wanted to disappear under the table. Not only did I insult him I called his bluff but for the wrong reason and took his money too.
