Mario Perez, the provocateur, presents another stomach-churning challenge, "asco de leche," with his friend Javi as the unwitting participant. The room is filled with a mix of laughter, disgust, and awe as Javi, with a grimace, starts to consume the leche, one mouthful at a time. Mario, ever the showman, encourages Javi, his eyes gleaming with mischief, as the challenge progresses, leaving the audience in a mix of disbelief and entertainment.
