Some Johny guy?

I had fun with this one and did it in an hour and a bit or so. I didn't zoom in until the very end and its a decent likeness although... the more I look at it now the more I realise I could fix up a few things.

People may not even be able to tell who. His face is supposed to be a bit longer and his jaw fuller. His eyes should be a little softer. His ear is a little too big. His jawline too angular. Lips slightly wider and less tall. Other than that I'm pleased. I may rework him a bit some time.
I honestly don't know exactly who anyways. He is an older actor. Any guesses?


Edit: I think this ~may~ be Johnny Carson.
