A/N:This story was based on this prompt given to me on tumblr: "PENGUIN SPONES PLEASE THANK".
Outfits for an Occasion
"Leonard," Spock spoke as the man in question fussed with his bow tie, "why must we wear these outfits?"
Bones laughed and moved his hands to straighten Spock's jacket. "Because this is what people wear when they're getting married where I come from. I wore the robes on Vulcan, you can wear a tux on Earth."
"The robes worn in Vulcan marriages are necessary for the bonding process. Please explain the significance of this attire."
"You know," McCoy said, "I don't think I really know why we have to wear these things. But you sure look fine, Mr. Spock."
A twitch of the lips that definitely wasn't a smile. "I see. I thought perhaps it was linked to those Earth birds that do not fly."
Bones frowned for a second. "You mean… penguins?"
"Yes. Do we not resemble these creatures?" Spock asked, gesturing to his outfit.
Leonard couldn't stop himself from laughing.
Spock certainly did not feel pleased with himself for making his new husband laugh.
