• Scott : There's an old, old saying on earth, Mr. Sulu: "Fool me once, shame on you; fool me twice, shame on me."

  Chekov : I know this saying. It was invented in Russia.

  [smiles devilishly] 

• Scotty : On Earth, we have a saying: Fool me once, shame on you. Fool me twice, shame on me.

  Chekov : I know this saying. It was invented in Russia.

• Chekov : Mr. Scott. Picking up something on the sensors, sir. Seems to be another ship.

  Scott : Well, let's put it on the screen.

• Chekov : It should be on our screens by now.
