Dean shifts in his seat, making the chair squeak.
"Stop moving," Sam orders him.
"I'm bored and my ass is sore." Dean complains. "It's boring doing research."
"Then get out of the motel and go for a drive or something." Sam offers, looking up from his laptop.
"Then you're going to be left alone with the research and I can't do that to my little bro." Dean says innocently.
"Yeah… but…" Sam says, exasperated. "Whatever."
There is a blessed silence from Dean.
"Want to hear a joke?" Dean's voice breaks silence a few moments later.
Sam knows when Dean is bored of the research, he will keep bugging him until he gives in. "Sure"
"Why don't sharks attack lawyers?" Dean says, grin evident on his face, even if Sam can't see his face.
"I don't want to hear another lawyer joke," Sam says sternly.
"Well, I want to tell you one." Dean says nicely, "Sharks don't attack…"
"Well, I'm not listening." Sam says before plugging his ears "La la la la…"
Dean tackles Sam to the ground. Plastering himself on Sam to prevent Sam from getting up.
Sam then uses his height and flips Dean over.
Dean uses the momentum and keeps the roll going to stay on top. He then uses his strength to keep Sam down, despite Sam's struggles. After a few minutes of struggling, Sam stops.
"I give up," Sam says, "Uncle."
Dean leans in, bringing his face close to Sam's. "The reason sharks don't attack lawyers is," Dean pauses for effect "for professional courtesy." Dean grins and gets off of Sam. He gets up and continues doing research like nothing happened.
Sam is left exasperated on the floor.
