Glutton for Punishment is a program on Food Network hosted by Bob Blumer and produced by Paperny Entertainment. The show features the host in various food-related challenges. He is given five days to become proficient enough in the episode's featured specialty. His newly acquired skills are then put to the test by matching him up against champions and experts in the field. In several competitions, Bob Blumer surprises by qualifying ahead of many pros. When he is not doing so well, he acknowledges the difficulty he has, often with self-deprecating humour. The "Glutton for Punishment" crew most recently broke the Guinness world record for the largest bowl of salsa at the Jacksonville, Texas, 26th Tomato Fest on June 12, 2010. The final bowl weighed in at 2,672 pounds. The feat was filmed for Season 5 of "Glutton," during which Bob attempted to break six world's records.
