"Infinite Challenge" has always prepared a delightful present for its viewers at the end of the year. This year, it is preparing a calendar event and a year-end concert. It's not the first year-end concert for "Infinite Challenge." It held a thank-you concert on Christmas day in 2007 and the You & Me Concert the following year. In 2010, it organized the Christmas Single Party to console the lonely singles during the holiday season. Last year, the crew held "I Am Almost a Singer," a parody of "I Am a Singer," and invited the audience to evaluate their performances.  

This year, Park Myeong-su, a.k.a Bangbaedong Wildcat, will lead the concert as a rookie composer. The viewers were immediately intrigued when they heard that the concert will feature songs composed by Park Myeong-su, who has released albums but never composed before. The members of "Infinite Challenge" are busy preparing for the concert but are still managing to squeeze in the time to deliver their annual calendars for the viewers. Making a calendar is their annual project. Last year, the members delivered the calendars themselves and met the viewers personally.
