I thought they got paid something to do those endorsements, maybe at the very least they give them a year supply of Jenni-O turkey.
Bob can be mad about Dolvett copying him, but it looks like Bob is copying Jillian now. The entrance with the motorcycle in the first episode is a similar entrance Jillian did in I think it was season 4.
I'm not sure about the red team making a 95 pound bet, they said they didn't know poker much so it seemed like they didn't know what they were doing and just bet anything. It also seemed like maybe they didn't know how much 3.8% would be in pounds...they probably just didn't want to admit to the camera and everyone they made a mistake lol
