The white elephant in the middle of the room.
With all his money you would think he could afford a better toupee. Wonder why no one says anything?
I understand it though. No one wants to be the guy who points out the white elephant, lest that white elephant delivers a roudhouse kick to the throat. He has got to know that we know, doesn't he? You can't take your eyes off it. Hard not to offer it a bowl of milk or something.
Suppose it isn't as bad as The Donald. I don't care how many helicopters he gets off of without that hair moving. It is a comb-over, albeit, an expensive 'weave' comb-over, but a comb-over none the less. Your not fooling anyone.
