"On the road again

Goin' places that I've never been – C'mon Sammy! Sing it with me!"

"No."

"Oh stop being such a hard ass. I know you know the lyrics."

"I am not singing Willie Nelson with you, Dean."

"What's wrong with Willie?"

"Nothing. I just don't like this song."

"Really." Dean glanced over at his brother. "Well, then I guess I'll have to force you to like it!"

Dean leaned forward a bit and cranked the volume all the way up, to the groaning despair of his brother.

"On the road again!

Like a band of gypsies…"

And just like that, the music stopped.

"Dean you are going to ruin your and your brother's hearing if you keep playing music so loud."

The two in front jumped simultaneously. It seemed no matter how many times it happened, they would just never get used to Castiel appearing out of nowhere.

"God, Cas, how many times have I told you to stop screwing with my tunes?"

"The same amount of times I have told you to stop saying my father's name."

Dean jumped even more in his seat. A very unmanly blush dusted his cheeks and he turned his head so Sam wouldn't see. In doing so, he also didn't notice the all too knowing smile on his brother's face. "I don't remember that…" He muttered.

"I told you last night in the room after we-."

"And I told you what happens in Vegas, stays in Vegas!" Dean cried angrily. Sam was choking on laughter. Cas just looked exasperated.

"Dean, we were nowhere near Los Vegas last night, I don't understand what you were trying to say."

Dean slammed his head against the steering wheel as Sam collapsed against the dash, almost sobbing with laughter. Castiel just sat there wondering what was so funny.
