 Oh That Hair! 

Can we have a little humorous mention of how Kirk's hair miraculously got bushier and thicker with old age? Encyclopedias can be coyly humorous, can't they?   
Yes, they can. However, we aren't Uncyclopedia or Monty Python; we are at least striving for legitimacy, so making jokes isn't always the way to go. If you want to cite that Shatner wears a hairpiece, then feel free to do so - in the William Shatner page; there has been no mention of Kirk wearing a rug. Until there is citation to that effect, we cannot include it. -  (cast a spell) "
