It would stand as the most glorious day in the history of the Enterprise, the day that the command crew found out that Ensign Chekov did, in fact, talk in his sleep. This discovery happened because Kirk thought that it would be a fantastic idea to have a "Crew bonding camping extravaganza". (When this was initially suggested, Bones nearly killed him with all the hypos).
How he actually got anyone to agree was anyone's guess.
Sulu woke up everyone accept Pavel ("God dammit Sulu, I need my sleep!"), and gestured for everyone to shut up and look at Pavel.
Pavel suddenly sat up, looked around, said "Kitty cat" quite matter of factly, And then promptly laid back down.
Everyone was trying, and failing, to muffle their laughter. Uhura and Kirk were failing the most extravagantly.
"Meep. No more butterflies, they kill me with their rainbow colors!"
Everyone just lost it, and it was a wonder that poor Pavel didn't wake up.
"P-Pavel, Pavel" Sulu managed to get out amongst his giggles, "Who's your favorite crew member on the Enterprise?"
"Scotty. He lets me help vith engineering, and let's me have some of his drink sometimes. But, shh! Don't tell Doctor McCoy. He'll give me a lecture."
Bones looked ready to murder someone, but he was silenced. ("But that's not healthy, god dammit!")
"I vonder what we will eat for breakfast tomorrow. I hope it's cantaloupe. I vould really enjoy that"
(Poor Chekov could never understand why the crew would always try to give him cantaloupe after that camping trip.)
