As a big fan of the show QI, the newest season is said to start first week of February on Channel 2.
Some years I would check the wiki site for any episodes that were in a location I was going to be in for BotCon... never ended up going to any though.
After watching his new series (Man Finds Food) late last year, he certainly lost a lot of weight after he finished this older series of his (Man Versus Food). I think he realised how unhealthy it was eating all those unhealthy and oversized foods, so got himself into shape and changed his show into secret eats (which aren't always bad foods, nor require him to eat massive items).
