This story takes place before the events of Where No Man Has Gone Before (TOS S1E3) because in that episode, Spock is wearing a yellow shirt.

The officers of the Enterprise sit at their posts. Kirk enters the bridge.

Sulu: Captain on the bridge!

Spock enters the bridge, wearing a yellow shirt. Bones thinks he knows what is going to happen next.

Bones: Oh god please no.

Kirk: Spock! You and I are wearing the same shirt!

Spock: Precisely, Captain.

Uhura: (Quietly) Please don't fight.

Spock: What's wrong with that, Captain?

Kirk: Nothing, Spock. I just wanted to point that out.

THE END.

Did you think I was really going to make a Star Trek TOS version of Brawl in the Family? I would never do that! If anything, I'd rather watch Spock's Brain 1,000 times than to remake that crappy episode not even Bob the Builder could fix. What should I make next?
