Jo Se-ho's 100th Day Celebration & I Wanna Be A Celeb

The members throw a party for Sae Ho to celebrate his 100th day on Infinite Challenge. Instead of throwing a regular party, the members decide to copy the theme of a party that's traditionally thrown to a baby after its 100th day. For the next half of the show, Celeb Five joins to perform their new single, "I Want to Become a Celebrity".
