* What's Blank looking for in his old high school locker? It looks like some splinters, but it's not too clear what it was.
** Weed, dude. It was weed.
*** More specifically, it's an old joint.
* What the hell is the whole "POPCORN!" thing about? Why does he keep saying that?
** That's the sound of two rapidly-fired semi-automatic pistols.
** He's also insane.
** "Popcorn" refers to expendable mooks, cause they're cheap and get munched quickly. Grocer is saying that Martin isn't special, just popcorn...which kind of goes against his obsession with bringing Marty on board, but again...he's not quite all there.
*** No, Grocer says it when firing or miming firing his twin pistols. It's the "pop pop pop" of gunfire.
** And that he finds gunfire perversely entertaining -- popcorn fare.
