Your worst nightmare
Dean woke up in yet another crappy motel, listening to Sam snoring on the other side of the room. He wanted to go back to sleep, but again he heard the sound that woke him up.
Giggling.
"What the hell?" he sleep-mumbled. Sam shifted in his sleep. Dean sat up in bed and peered out the rooms only window. He heard a muffled "squee!" and then a "shut up!"
"Who's out there?!" he yelled. More giggling. Enough is enough dammit! Dean get up and flung open the door. There wasn't anyone in sight. Dean stood in the doorway looking for a few more seconds, then he slammed the door.
"Whadja do that for?" Sam said muzzily. Dean looked at him.
"Going crazy I guess. Time to get up anyway!" His little brother growled at him. "C'mon! Rise and shine!" One of the great joys of Dean's life was tormenting Sammy.
"Only if there's food…" He said. Dean grinned.
"Fine, I'll get you something from the vending machine outside. Happy?"
"No" Sam grumbled.
Dean left to get the food, knowing that whatever Sam said he would be (mostly) awake by the time Dean get back. He took longer than he needed picking out the kind of chips he wanted before going back to the room.
"Dean, where's my hairbrush?" Sam asked when he walked in.
"How should I know?" He replied, "in case you haven't noticed, I don't have enough hair to brush." Sam sighed and took his funyuns from Dean. They got a call reminding them that today was checkout day and began to pack up.
"Sam, where's my toothbrush?" Dean yelled from the bathroom.
"I dunno." said his brother. Soon the realized something was wrong. By the time they were packed the were missing, besides the tooth and hair brushes, Deans favorite shirt, Sam's wallet and two of his books.
"This can't be a coincidence." Said Sam.
"Ya think?" snapped Dean. Time to call in the big guns. He hit 2 on his speed dial.
"Bobby? Its Dean, we need your help."
