"Sam have you seen my metallica tshirt?"
"Your pink one?"
Dean glared at him, "NOO My red one."
"Yeah see! When you did the laundry I saw you put the red shirt in with the whites. I guessed the color bled out and it became pink. I figured you didn't want it anymore so I dumped it in the trash!"
"YOU WHAT! How could you trash it Sam! Why didn't you say I put it in the wrong pile?"
Sam snuck out a "you didn't ask me" before he ran out the door, with Dean in hot pursuit.
