"Dean," Cas said.
"Yes?" Dean asked.
Cas frowned. "Dean, I have something stuck in my head."
"What is it?"
"Assbutt," Cas replied.
"Assbutt?" Dean repeated.
"Assbutt," Cas confirmed.
"That's a word," Dean said.
"It is a word," Cas answered.
"You got a word stuck in your head?"
"Yes. The word assbutt is stuck in my head."
"You can't get words stuck in your head."
"Dean, the word assbutt is stuck in my head."
"Assbutt?"
"Assbutt."
"I don't understand."
"What don't you understand, Dean?"
"How did you get a word stuck in your head?"
"I just did, Dean."
"That doesn't make sense."
"Why not, Dean?"
"It just doesn't."
"You're an assbutt."
"Thanks, Cas."
LET ME JUST SAY.
THAT I WROTE THIS AT TWO FREAKING AM.
AND I HAVE NO IDEA WHY THE HELL WHY.
