I would love some help if anyone happens to know what the sunglasses Jack Nicholson is wearing at the 2007 Oscars on stage with Diane Keaton.

Link to picture page with several pictures:

I don't know what they are, but imho they will look like crap on almost anyone else.
They don't even look good on him, and he's Jack Nicholson.
