In one of the segments, a member of each team came up as representatives to play a game which involved shouting a number that differed from the number of fingers they held up. For example, an individual would shout the number 3 while holding up 1,2,4, or 5 fingers, anything but 3 fingers. SHINee's Key and One Seong Wu faced off.
The two intensely started but finished quickly as Key pointed out Ong Seong Wu's mistake. The Wanna One member became confused and taken back. Subsequently, he reenacted what he just did to prove he didn't lose but immediately realized where he messed up and was at a loss for words which made the rest of the cast burst out into laughter.
