Honestly, they should continue that bet throughout the campaign season. Let them bet on New Hampshire. If Stossel loses a few, that's fine. It would get some good press.
The point is that O'Reilly is a cold hearted bastard, the type of guy who I don't think has any fun. If they could make this into an ongoing joke, with a charity making lots of money off of the process, it will lighten him up a little.
