saw this ages ago. Wonderful display of "do you know who I am"? - ism.
I remember a good few years ago in the 90's a guy I worked with was at the home of a certain well known in the 70's entertainer ( ok it was Kenny Lynch ) when they entered into a professional disagreement as to a judgement made. My then colleague was in his early 20's was asked " do you know who I am? " At which point my then colleague responded with a genuine "no I don't" - seems that then properly hit the blue touch paper !!
