After the "Spinal Crap" comment, James and Doug do a slow routine of drinking from their cups, setting them down and wiping their mouths, all while staring at the camera. Towards the end of this routine, it's highly noticeable that James is trying not to laugh.
Doug misspells the title when speaking with Rolfe synchronously by saying "coming out of our shell" instead of "their" whilst James spells it correctly.
