My wife saw an ad for this show on the Food Network called "Glutton for Punishment" where the guy does weird challenges and events. On Oct 20 at 12:30PM (mountain), they are doing a replay of the "Guiness Diet" episode, in which the host consumes nothing but Guiness for a week just to see what happens. No food, no other liquids, etc. Should be fun to watch:

Note: the site schedule doesn't have this one listed for the 20th, it has a different one, but my Tivo guide says it's the Guiness episode, you may want to double check your guide.
PS - I know Justin has done this before, but this time it will be professionally documented and it won't be PBR.
