I find this adorable, but it did surprise me. They almost always, with like a 10% exception, walk in the same order no matter what they're doing. Zak is in front, Nick in the middle, and Aaron in the back. I think it's because Aaron's also the tech/camera guy so it makes sense to have him in the position where he can cover everything, but I've seen times when they start walking from a bit of a huddle and they go right into that order.
Anyone wanting something serious on this one obviously doesn't know me very well. I pick out the oddest things.
