I remember when this was first posted, I only played the clip once or twice, but I remember thinking, "I can't fucking tell the difference and I'm not going to sit here and stare at it long enough to figure it out, if I even can." But this is hilarious. I especially hope the individuals pictured below take this to heart and learn something. The one that says, "it's off-model most of the time" is my personal favorite. Because that poster used industry jargon to create the air of expertise. And the smugness with which it was delivered was...>chef's kiss<. Beautiful.
