I'm there! Yes, "Piece of the Action" is true delight!

Of course when an episode comes back to haunt the characters in another version of Star Trek, then how can you discount "Trouble with Tribbles"? (I am remembering the reaction in Wharf when they played those "old tapes", refering to the way that the Klingons looked like - when the-powers-that-be did not have either the imagination or budget).
