Hurl!

Format

The show begins with an unidentified person shopping for food and purchasing the food for the current episode, with a narration about competition. The intro ends with the clerk asking "What are you going to do with all this stuff?"

Prior to the game beginning, some information is provided via the narrators and on-screen text. All on-screen information for the viewer is done by holding up a post-it note or a notebook with handwriting on them. The "one simple rule" of the game is incorrectly described by the narrator as "whoever eats the most and hurls the least, wins". In fact the winner is the contestant that eats the most and hurls the last or not at all. Five competitors are introduced by name, height, weight, and occupation. The five begin the game by eating large quantities of food, usually a single savory dish accompanied with a drink to help wash it down. All food and drinks are identified as being organic. The food is placed on deli scales, which are used to determine through subtraction how much each competitor eats. Of the five competitors, only the three that eat the most in a span of five minutes make it through to the second round.

The second round involves some sort of physical or recreational activity, usually one that involves large amounts of spinning, for five minutes. The activity can end early if one of the contestants vomits. A "hurl" is defined on the show as any swallowed food that comes out of the mouth. If a player vomits into their mouth and it does not come out, it is not a "hurl".

For the third round, competitors return to the scales and eat for another four minutes. Sometimes they eat the same food as the first round, while other times they move to a second food item, usually a dessert. If three competitors make it to the third round, then the two that eat the most in the third round move on, unless somebody vomits first.

After the third round, if two competitors are left, a fourth round of extreme activities is done in a "sudden barf" format: first to "hurl", loses. Sometimes the extreme activity is done blindfolded to induce disequilibrium and nausea. If necessary, a fifth round of eating and a sixth round of blindfolded extreme activities are done as well. If both players make it through all six rounds without hurling, then the one that ate the most during just the fifth round wins the contest.

The game crew that runs the competition is called the "hazmat team". They are several people dressed in Level C hazmat suits, complete with gas masks, and act as a cleanup crew. Although they are dealing with bodily fluids, necessitating some precaution, their dress is exaggerated for comedic effect.

When a player vomits on-screen, the vomit is censored with numbered buckets and a pinball game sound effect. The buckets are used to arbitrarily rate the scale of the vomiting, up to an "epic five-bucket blowout" on YouTube, although in Episode 11, a contestant hurls while being spun by a Sumo wrestler, and the narrator observes that on a scale of 1 to 5 buckets, this was an 11 bucket hurl. They are usually (but not always) preceded by a "hurl warning" with a handwritten note in front of the camera and a Klaxon, which also is sometimes used with close calls and fakeouts. The show also shows various "strategies" employed by some players to either eat more food or try to induce other players to vomit. Each strategy or technique has a number that is shown to the viewer on a handwritten note.

The last one remaining wins $1,000, which is paid immediately in cash by "Manny" (Manny Salcido), the leader of the hazmat team. If the winner also ate the most food in the contest, then they also win the "Iron Stomach Award". Sometimes the winner will vomit after their win; since they already won, this does not affect the outcome of the game. The show will also depict competitors that have lost and vomit after being eliminated.

The G4 network aired all 11 episodes in an uncensored (no buckets and no sound effects) format after the censored episodes had been shown.
