3. Andy Kaufman

If there was a celebrity who totally immersed himself in wrestling more than Andy Kaufman did, we have no idea who it is.  His feud with Jerry “The King” Lawler was legendary and he played a heel better than the bulk of the WWE roster today.  Kaufman loved the business so much he pursued it at the detriment of his own career.  An induction to the Hall would be a nice posthumous gesture to someone who loved wrestling so much.
