After trying to guess the answer, the two gave up and decided to use their 'As a host' lifeline, in which Jimmy himself had to assist. Matt's faux feud with Kimmel led him to believe that their use of the lifeline was going to render useless. However, when Kimmel said he knew the answer to the question and was 100% sure about it, the Martian actor changed his mind.With Jimmy's help, the two locked in on the correct answer, which was Bill Nye, and won $500,000. For the next $1 million question on Who Wants To Be A Millionaire? Matt and Ken needed help again, and this time they went for the '50-50' lifeline. The question was,"Which of these words is often used to describe one of the most beautiful auditory effects on Earth: the sound made by the leaves of trees when wind blows through them?"The four options to the question were Apricity, Petrichor, Susurrus, and Eudaemonia. After using the lifeline, Ken believed that the correct answer was Susurrus. While Matt had no say in it, he trusted and went with Ken's answer.
