Dean was working on Baby. He hears Bobby's voice in the backround but only tunes in on, "I just wanna help, since I made you this way!"
Dean snaps around and says, "Bobby, you didn't make me guilty. You know what makes a person guilty? Killing things. But I guess you'd know all about that, huh?"
Bobby's face is one of total betrayal, before Moose - oops, not Moose, Sam - appears and whacks Bobby with a shovel, knocking the bearded man out. Dean blinks at Sam, "Oh, hi Sammy."
Sam nods, "Hey."
Then, when Dean blinks, there's people appearing and grabbing at his brother. "Dean! Little help?"
Dean looks at the people, then at his brother, "Sorry Sammy - FUCK THIS SHIT," Then he runs into a little white house that appeared out of nowhere.
Sam watches his brother run away, and pouts. He gets kicked to the ground, and huffs. "No." He knew what he had to do. He closes his eyes, and feels wings springing out of his back, his body sprouting feathers, and his mouth and nose becoming a beak. "Caw, caw, motherfuckers." He then bats his wings and flies into the sky. He flies to a school, and goes in LIKE A WRECKING BALL right through the window. "CAW CAW LITTLE KIDDIES!"
He sees some asshat picking on a little girl, and picks them up with his talons, breaks their neck, and pecks their eyes out. Then he drops the body, flying over to the girl, giving her a little bird-nuzzle, then flies out of the window again into the sunset.
The End?
