Which is exactly what The Office was.
When it was first aired the adverts on the TV & media just said it was a 'fly on the wall in the day to day running of an average office'.
Since me and the wife watched these type of documentaries we tuned in and kept looking at each other.
It was 10 minutes before I thought I recognised the Manager, hit the internet and realised it was the stand up comedian out of Not The 11 O'Clock News (!!!).
The following day work mates were asking me if I saw that weird documentary with the weird Manager and then I explained.
