No No No Apple...UK needs cynicism. This is all a bit Daphne in Fraser, as quaint as the English pub. Americana has to be american for Brits to accept it. Were the "Little Britain" cast fully booked? Cleese for PC at least. Last time I looked the roles should be reversed in UK. The trouble is that this comes across as young vs. old. The younger man is no way trendy in UK terms, just steaming full ahead to become the older guy. The appeal of these adverts to US is that they openly take the mick out of the establishment (M$) in the public domain. It is just not necessary in the UK, its not a shock tactic here it's a way of life.
I agree. A complete role reversal might be a little more effective by appealing more to the distinctly British sense of humour. The Mac could be even more reluctant to look good, and actually try NOT to convince anyone, like his job interview clip linked earlier on in this thread.
For those that say the British are quintesentially sarcastic, I have to disagree. We are simply ironic. Sarcasm is related, but to me tends to be all in the tone of voice - anyone who says "yeah, right dude, whatever" in an ascerbic manner is being sarcastic. AS such, I think sarcasm is a very American trait. Good irony is usually self-effacing on the surface but the real intent takes a couple of days to register, and often goes completely over the head of its target.
