L.A. Beast practiced for a month leading up to the Guinness challenge by chewing on dried ghost peppers. (See him in training in the teary video above.) In case you're considering an absolutely stupid challenge like this, Beast, a ranked competitive eater, says he pretends he's on a beach sipping beers in his mind while his body does "all the work."
Even with that professional advice, you should probably skip this challenge. L.A. Beast is an animal and look how his hands are shaking toward the end. The experience looks thoroughly unpleasant even before he starts chugging milk and has to run (presumably) to the bathroom while being told he broke a world record.
Someone mail that man a pallet of Charmin.
