Yeah they look like
rent-a-kind-crowd. Not really real people. Just paid for
'we'll be very nice' peeps.
I accidentally saw the 65th birthday of Blue Peter on TV yesterday and they had kids on that. All of them look like they'd be drafted from
rent-a-happy-jolly-kid inc.
I guess it's safer to do it that way. The kids don't look bored like they used to do when they used real schoolkids. That was back in the 1970s and 1980s kids TV shows you can see on YouTube.
