Haven't developed any strange twitches that I know of yet.... but then I've only been playing 4 months.
Come to think of it I have emulated Hammock's dance routine on a few occasions... they always involved an Orb Weavers web though.
Seriously, Hammock's credentials speak for themselves.
Reminds me of a girl my daughter played basket ball with. She has this little ritual she would go threw before every shot when she went to the free throw line. I dubbed it 'Abby's Chicken Dance'... she could could shoot the lights out.
