After a particularly taxing mission, Kirk decided his officers need a breif reprieve.
That evening Kirk planned a small get together to celebrate the missions success. The party was small and consisted of Kirk, Bones, Scotty, and Spock. He had invited Sulu, Chevok, and Uhura too, but they had said that they were either busy or too tired to go. Various types of alcohol we're being served and everyone was enjoying a white chocolate and caramel cake.
Upon everyone finishing their dessert Spock glanced at Kirk, who had made the cake, and asks, "What kind of cake was that? It was good."
"Thank you. It was a white chocolate and caramel cake," Kirk replied, his chest puffing up slightly like a proud bird at the compliment.
Spock's gaze abruptly snapped over to the captain, him eyes widening a fraction "Chocolate, sir?" He asked.
Kirk nodded, "Yep. White chocolate to be exact."
Spock took a moment to digest this information before getting up from the table. "This has been a pleasant evening, but I really must go now." Spock said, seeming to be in and unnatural rush.
"Is something wrong, laddie?" Scotty asked.
Spock shook his head ever so slightly. "Not wrong, per se. Simply an oversight on my part. Vulcans can not have chocolate."
Jim paled, worry flooding through him. "It's not like, poisonous to you is it?"
Spock shook his head once more. "No Captain, not poisonous. The best analogy I can give is… Humans have alcohol, Vulcans have chocolate... Now if you'll excuse me we really must go. Lest it be my embarrassment and your discomfort." (Bonus points to anyone who can tell me where that semi-direct quote comes from.)
Without waiting for an answer, Spock quickly exited the room. However, about halfway back to his quarters the chocolates effects redirected him down another hall and eventually into rec room three.
"A drunk Vulcan... Does anyone else feel like that would be incredibly entertaining to see?" Kirk asked.
The others all smiled at the mental image that statement produced.
After the party was finished, Dr. McCoy decided it was wise to check in on the commander, just to ensure that he is alright. However, upon finding that Spock is not in the quarters, the good doctor immediately set out to find him. Bones did in fact find the missing Vulcan in rec room three, however upon discovering what a peculiar state he was in he immediately commed Kirk.
"Jim. You need to get down here and see this. I am in the doorway of rec room three. And honestly, I don't believe what I'm looking at." He drawls in his southern accent.
A few minutes later Jim, Scotty, and Uhura, who had been woken by Scotty and asked to join the search, came walking down the hallway only to freeze at the sight of the commander.
Spock was sitting upside down on the couch wearing only his underwear. His clothes were laying in a heap on the floor. That in itself was shocking. Howeve, the most off putting thing was that the normally straight faced commander was laughing hysterically.
Upon seeing Kirk, Spock attempted to stand up. "Capt'n" he shouted in mirth, only to realize that he was, in fact, upside down on the couch and only managed to fall to the side instead of standing up. This, of course, sent him into another fit of giggles.
"Commander Spock, why have you removed your uniform in the rec room." The captain asked genuinely curious. And thankful that all of the off duty crew members were currently in their bunks, knowing that the commander would not want anyone else to see him in such a state.
Spock suddenly looked to him with the most serious of looks. "I don't really like clothes!" He replied. "Too many tunnels!" He screwed up his face into a disgruntled expression.
"Tunnels?!" McCoy choked out, trying desperately not to laugh.
"Yeah!" Spock enthused. "Pants are… Are just two long tunnels stuck together! And shirts... Shirts are just one, big, fat tunnel what's two tiny skinny one stuck to the sides of them! It's ridiculous!"
McCoy, Scotty, Jim and Uhura all exchanged amused glances, trying hard not to laugh. However, as Jim's face turned red in the effort, Uhura let out a most unlady-like snort, sending everyone into a fit of laughter. "Oh-oh my... I-I'm so sorry..." she got out between giggles, apologizing for the snort.
