Dean walked into the motel room to find his brother very, very drunk, and very, very giggly.
"Hey, Sam, how's it shaking?"
"What's shaking?" Sam piped up with a grin, sitting straighter on the edge of the bed.
"Hopefully, nothing." Dean gathered up case notes and began taking down the things they had pinned to the wall. The case was over, time to move on.
"Hey. Hey Dean. Hey. What do you want for dinner?"
"I dunno, Sam, what do we have in?" Dean sighed, not really in the mood for happy!drunk!Sam when they'd completely botched up their latest hunt.
"Well, we have spam, spam, eggs, sausage and spam. Or we have spam, spam, spam, spam, beans, sausage, and spam. Or we have…" Sam's voice changed from a high-pitched wail to a deep singsong, "spam, spam, spam, spam, spam, spam, spam, spam, SPAMMITY SPAMMMM, SPAMMITY SPAMMM! SPAMMITY SPAM, SPAMITY SPAM!"
"Okay, Monty, that's enough." Dean smiled and pushed his brother back onto the bed so he was lying down. "I'll just grab us some stuff from the diner, 'kay?"
"Get me some spam!" Sam giggled.
"Dude you laugh like a girl," Dean was starting to chuckle a little himself. It was hard not to love happy!drunk!Sam, after all.
"Your mother was a hamster and your father smelled of elderberries!" Sam replied gleefully.
"I fart in your general direction!" Dean jumped on his brother and started tickling him like they used to when they were kids. Just as it was growing into a full-on wrestling match, a flutter of wings interrupted them and the boys went still.
"I heard about your hunt, I'm sorry it turned badly," Castiel's voice was gravelly and solemn as usual.
"Yeah, damn witches." Dean was brought back to the present by the angel's condolences.
"Yeah, she turned me into a newt!" Oh crap, Sam was still drunk off his ass, and Dean was fighting a smile as he retorted with the next line-
"You don't look like a newt." Castiel beat Dean to the punch. But instead of his usual emotionlessness, Dean saw him fighting a smile too…
"Wait, Cas, how the hell do you know about Monty Python?" Dean was incredulous.
"He's a crowd favorite in Heaven, Uriel showed me his work when we were fledgelings." Cas's face darkened again at the mention of his now-dead brother. "Why the sudden inquisition in angel life, Dean?"
"NOBODY EXPECTS THE SPANISH INQUISITION!" Sam yelled drunkenly from the bed.
And for a few shining moments, the night rang with the laughter of three boys in a motel room.
