Watching people watch telly

Who would have thought that this could be so entertaining? I certainly didn't!
I stumbled on this programme by coincidence: Gogglebox on Channel 4 and my initial thought was: who would want to watch this?

The programme shows a number of people watching telly. It's the same people watching telly each week and you get to witness their banter and shouting at the TV. That's it. Sounds pretty daft, but it is really rather funny. Or at least I think so.
