Imagine you're in one of those cheap motel rooms where… oh, I'm sure you all know what a cheap motel room looks like so there is no need to write about it. And through the thin motel walls you can hear almost everything.
„Sam?"
„Yes, Dean?"
"There was one piece of pizza left in the box yesterday"
"Yeah. So?"
"And it's not there now"
"You must've eaten it"
"Me? When? I don't remember eating it"
"You should read more Dean. Reading will improve your memory"
"My memory is just fine, thank you. Admit it, Sam, you've eaten it"
"Me? When? I don't remember eating it and I read a lot, so--"
"--so it's a proof that reading messes with your brain"
"But I do remember strange sounds coming from your bed last night, Dean"
"What strange sounds?"
"Sounds like… This kind of sounds you make, when you're eating a pizza"
"I don't make any sounds when I'm eating!"
"Oh yes, you do. I even recorded them"
(after a few seconds of silence you can hear recorded smacking)
"That's not me!"
"It's you, Dean. And if you looked for it, you'd find the crumbs of pizza in your bed"
"Yeah right, and why the hell did you record it?"
"Because! First of all, to have a proof that you ate the pizza in case you accused me; second, to show you how awesome brother I am living with you"
"You would be an awesome brother if you brought me a new pizza"
"Well, I couldn't sleep, so I went out early this morning. Here you go, I bought you pizza. What were you saying, Dean?"
(the sounds of the smacking but this time not from recorder)
"Awesome pizza, Sammy, I'm telling you"
