Jim Beaver can actually speak Japanese . i thought i couldn't fall in love anymore with the cast of Supernatural than I already have but I was so wrong -- actually I think he says before you were born but. His body language said screw you.
I absolutely love the fact that Bobby's favorite memory is not of a spectacular creature kill, or of the boys surviving a particularly nasty case, or anything hunting related. His favorite memory is the boys just being boys, being normal brothers.
