Sharpe is described in at least three books by former wrestling personalities (Tom "Dynamite Kid" Billington, Hulk Hogan and Gary Michael Cappetta) as having shown characteristics of obsessive-compulsive disorder, as evidenced by a preoccupation with cleanliness that caused him to spend hours washing his hands or showering at arenas and meticulously folding and re-folding his clothing. According to Cappetta, Sharpe's behavior earned him the nickname "Mr. Clean" among his co-workers.
