Simon and Garfunkel sang a song back in the 60's "A Simple Desulatory Phillipic." The song had a line, "Communist cause I'm left-handed, but that's the hand I use, well nevermind."

Write - left
Throw - right
Bat/Golf - right
Guitar - right
Eat with fork - right
Eat with chopsticks - left

I can twirl my index fingers in opposite directions. I can do the Laurel and Hardy routine; right hand on left ear and left hand on right ear and then switch. :p
