Yes, I imagine there wasn't any further laughing after that point. I was there one time while the changing of the gaurd was going on and something like that happened. There are stairs that lead up to the tombs on the opposite side from where people stand to view the change. Someone was trying to get a better view and was actually coming up the stairs (not good). The staff sergeant who was doing the change stopped everything faced the intruders and said, "IT IS REQUESTED, YOU GET OFF THE STAIRS!!" They backed off in a hurry! I guess, "It is requested" is what they say in those situations because I've seen it twice now (including this video.) Thanks, Vee!
