I think it's Stephen Keaton from Family Ties. Makes sense: an aging hippie who started the Darma Initiative utopia in his youth.

A. Hanso..

is it a cat or something in front of his head, on his shoulder or is it a piece of his head missing? oh man do i hope it's locke...dead...with a part of his head missing.

I did not even see Jacob the first time I watched it. Then I watched it again but with the commentary they said you could see it and i slowed it down. I would kind of agree with Christian Sheppard.
