Here in Norway they're currently running The Biggest Loser: Couples Edition, and being the trash-tv junkie I am, I occasionally plunk myself down in front of it. It has the most shameless product placement of any show I've ever seen, ever. In my life.
They do this thing where one of the trainers gathers their team and pretends to be teaching them about, say, nutrition, but instead just tells them that Ziplock bags helps keep food fresh using their patented blah blah blah system, AND IT SAVES YOU MONEY!
Just about every episode has something like this, with the contestants saying something along the lines of "it just makes sense" or "oh wow, that's great!" It's like a tiny little infomercial inside the show.
