Brian is specifically afraid of toilets, so Dr. Grayson's next challenge is for him to sit on the toilet seat in the cabin's bathroom. When Brian is scared, Dr. Grayson offers an alternative. "If you want, we can go in together and just rub our hands on the seat first and put our hands in our mouth."
Brian says this suggestion makes him feel like he's paralyzed with fear. Dr. Oz says he's ready to catch Brian if he passes out. "I may have made a huge mistake," Brian says. "I don't know if I'm going to be able to handle this."
