That is entertaining to watch. I am a bit cynical for several reasons.Holy crapola I found it.
Note - I have not watched anything else this guy has done. I just remember liking this video a lot (I don't even have time to watch it again now, have to go get ingredients for dinner)
Firstly, there must be at least THREE cameramen prancing around them; which would be a major distraction to anyone whom has NOT performed on camera before. If that is not the case it was shot several times (like a Hollywood movie) with different camera setups.
And, I would imagine if I was suddenly unable to write my name or unable to blow out air I would be in a panic! She appears to be suspiciously comfortable and secure (relaxed) with him; and at least three other people surrounding them with cameras.
