So for those of you who have been wracked with curiosity for more than two months over the meaning of their unintelligible and brief exchange, I give you the translation of their conversation (courtesy of Kahnn06)
Guy on left: "There are two idiots near you." (or "...two idiots to your left.")
Guy on right: "Yeah, I see them."
So if you were hoping for something scintillating...sorry.
