Detour on the way to the city on the edge of forever

The A.V. Club has an appreciation/analyses of the writer Harlan Ellison, with accompanying photograph featured above. Of course Ellison is partly known for writing the very best script/screenplay for a Star Trek episode, "The City on the Edge of Forever." Three questions come to mind when I see that pic:

1. Is Shatner gettin' him some?
2. Where are Spock and Kirk's insignia??
3. Were Nimoy and Shatner actually that much bigger than Ellison? They look huge.
