Dean's in the middle of a "WHAT DO YOU MEAN BY ASKING IF HE LOOKS LIKE THE CAR?!" style of rant (while Sam is caught between laughing his ass off and trying to read through ages of archives in the hopes of finding anything like this) when he hears the crazy commotion outside and peeks through with window.

... only to see the.. uh.. twins(?) fighting. If this wasn't turning into such a shit storm, he'd laugh at FDR's attempt to drag the other one onto the sidewalk.

"Sam, I gotta call you back," he says and hangs up before walking out there.

"Hey. What the hell are you guys doing? I walk away for not even a minute and you're fighting? STOP it." Man, he hates it when they force him to sound like the old guy.
