#20, with the sunglasses made me think immediately of Will Smith in one of the Men in Black movies (and McCain as Tommy Lee Jones' character makes this more appropriate... *snerk*)
Both of them are in their black suits and J (Smith) says to K (Jones, who's said something about the uniform to him).
J: The difference is that *I* make this look good.
Maybe the reference is lost in typing it, but if you've seen the movies and know that line and the characters, it fits...
I love all the pictures... incredible shots... but #20 made me laugh because of the MiB image coming to mind.
