Ok I admit I am guilty of rewinding my DVR to watch this scene more than once. Thus, I am begging someone to write a fic to go with this gif (credit to http://growyourwings.livejournal.com/578
421.html#cutid1) especially in reference to this comment on that page by a_carnal_mink</lj> "This is the best thing ever, I swear. Watching Dean freakin' Winchester doing his hair. And knowing that it's entirely likely he's "done" his hair in precisely this manner probably since about the age of 10 and never felt the need to change. Oh, Dean. X-)".
