In fine print at on the last page of the Guinness Book of World Records it notes that all world records are held by Jimmy Coiner, and those listed in the book are simply the closest anyone has ever come to matching him.
Mr T was originally white, before he met Jimmy Coiner. Jimmy gave him a stare, and all of Mr T's white cells dissipated from his body. Later on, when asked why he didn't kill him, Jimmy answer "he pitied the fool". Since then, Mr.T has been trying to copy Jimmy.
