In this day and age it's really rather sad how original ideas are neglected in favor of running this old twist once again. The reality telly RSPCA/Social service-workers save Marmite jars that have ended up in the way back of the pantry, to re-home them with families that won't neglect them. Aw.
It's really quite well executed... and just like with Marmite, you'll either love or hate the idea.
