At around 6.47 you will see Geoffrey Winder do the 666 sign, absolutely no need because he could have just put up 3 fingers together or not do any sign at all.
I saw the 2014 video too Lizzy, Mark does the triangle twice in a matter of seconds, he makes a point of doing it and again no need because he had his fingers intertwined to start with and he isn’t even doing the talking at the time 🤨🤨
