[Kamog]

The silliest thing about that episode was Scotty not knowing how there could possibly be light underground when there's no sun. The Chief Engineer has no clue what a light bulb is.

The other dumb thing was the remote control McCoy made to control Spock's body. It has about 4 buttons that have functions which are something like this: (1) walk forward (2) stop (3) turn right (4) grapple with nearby humanoid and take away their weapon.
