Panel 1: Lucky the unicorn dog sits in Captain Kirk's lap as Kirk reminisces: "I remember when having a Vulcan aboard ship was quite a novelty...". In Kirk's thought bubble, we see his former self wagging his finger pompously and saying, "Mr Spock has kindly agreed to join us in the rec room tonight. I want everyone on their best behaviour!".
Panel 2: Still pompously lecturing, Kirk says, "Above all, no ear-related humour!". Uhura, Chekov, Scotty and McCoy reply, "Aye, Captain."
Panel 3: The rec room. Spock is seated with his lyre. Uhura says, "Oh! What a beautiful lyre! Would you like some sheet music?" "No, thank you" replies Spock, stand-offishly.
Panel 4: A close up of Captain Kirk, who asks, in total innocence, "Oh, do you play it by ear, Mr Spock?"
Panel 5: Spock's icy glare at Kirk shows that he thinks the captain has just committed a micro-aggression. Panicking, Kirk stutters, "I- I mean-", while the room swims around him. In the background, Scotty and McCoy are laughing uproariously.
