Lee Eun-ji flirts with Yoo Seung-ho during toilet crisis
Cast members of EBS1's 'The Last Humanity' face a messy crisis when a toilet clogs, leading to hilarious banter between Lee Eun-ji and Yoo Seung-ho.
The cast of the EBS1 variety show 'The Last Humanity' was seen building a makeshift toilet to resolve an unexpected plumbing crisis inside their dome.

In the sixth episode of 'The Last Humanity,' titled 'Return of the Abandoned,' which aired on the 9th, survivors living with limited resources faced a major setback when the toilet became clogged.
The incident began with Jang Dong-seon. After experiencing abdominal pain and searching for a restroom, he discovered the clogged toilet and reacted with embarrassment, saying, "Since we live together, this kind of etiquette should be maintained."
With waste left in the toilet, the cast members reacted with a mix of shock and laughter.
Yoo Seung-ho joked, "I only saw it for a brief moment, but I made eye contact with a nut," while BIBI suggested a pragmatic approach, saying, "Regardless of who did it, finding a solution is the priority." Meanwhile, Lee Eun-ji lightened the mood with witty remarks, jokingly suspecting Jang Dong-seon by saying, "I think Dong-seon is acting."
Ultimately, the cast decided to go beyond simply unclogging the toilet and instead build a new waste management system. Jang Hong-je scavenged the warehouse for various tools, including ice cream scoops, sawdust, empty containers, shovels, fallen leaves, and gloves, to create a compost-style makeshift toilet.
When the group suggested splitting into a "toilet-building team" and a "waste-scooping team," Lee Eun-ji volunteered for the latter. When Yoo Seung-ho personally helped her put on gloves, Lee Eun-ji jokingly teased, "Seung-ho, is office romance possible in the dome?" Yoo Seung-ho quickly drew a line, causing laughter by replying, "I'm only putting them on you because you said you're going to scoop poop."
During the task, Lee Nak-jun and Jang Hong-je used ice cream scoops to transfer waste from the toilet into a container filled with sawdust. Jang Hong-je expressed shock, asking, "Is this really the amount a human discharged?" The situation turned into instant chaos when the container was dropped, spilling the contents onto the floor.
However, the cast remained composed and continued their work. Jang Hong-je eased the tension with a joke about chocolate cookies, and the team eventually finished constructing a fermentation bin by mixing the waste with sawdust, charcoal powder, and fallen leaves. The survivors' cooperation in overcoming the crisis despite the odor and discomfort drew significant attention.
Following the task, the cast participated in a draw for a bonus mission. The lucky winner was BIBI, who was assigned a special mission to wear a spacesuit and mine bonus seeds in the Hwa-seong yard. After completing the mission, she remarked, "After going there, I want to live on Earth even more."
The episode went beyond simple variety show humor, capturing the process of recycling waste and building a survival system in a limited environment, which further highlighted the program's survival experiment concept. The cast also left viewers with a sense of curiosity as they inferred that the previous occupants of the space were conducting real-life experiments aimed at migrating to Hwa-seong.
