Mustache
Spock scrolled through reports on his PADD, his eyes flickering over the touchscreen's bright surface and his mind totally consumed with his work. A certain figure crept up behind him, much to the amusement of several others who stood apart watching. Spock had been far too absorbed in his work lately, even for him, and they knew a good prank when they saw one.
The figure they all knew so well cleared his throat. "Spock, what do you think of my new mustache?"
Spock whipped around, totally startled out of his work. "Mustache? What are you-" his voice stopped short as he realized what exactly was on the man's face. For the first time in his life, he understood what a facepalm was, and even as his hand smacked his forehead he finished, "Sir, that's a Tribble. And it's duct-taped to your face."
A moment of shock followed before the reply. "What are you talking about? I'm gorgeous!"
The entire Bridge crew of the Enterprise burst out laughing, tears flowing down their faces and their sides aching. Kirk was the one to lead them all, the fuzzy Tribble duct-taped to his face purring happily.
It was McCoy who noticed, in the ensuing hilarity, that the hand in the middle of Spock's forehead had slipped down to hide his mouth.
Apparently even a Vulcan couldn't help but crack up at the sight of his captain's new mustache.
Hahahahahaha! Hi guys! Hope you loved this piece of pure, sheer, utter fluff as much as I did. :D Props go to a dear friend of mine who gave me the idea; she's an amazing artist and drew a comic of this scene for me, which I got permission to put in writing format on here. I changed it up a bit, but the awesomeness is still there. Please leave a review, and many happy days of fluffy hilarity to you all! :)
*Update* The friend who drew this goes as shadowfan36 on deviantart, so if you like Homestuck or Creepypasta stuff go check out her page! I attached a photo of the actual comic as a cover to this story, I hope you guys can see it. It's awesome :)
