With 2018 being the Year of the Dog, the show held a two-part special featuring vocalists who are dogs under the Lunar calendar.
Returning to the program after 4 years, Wheesung commented, "I am working hard like a dog this year." As for Hwanhee who appeared on 'Weekly Idol' for the first time, he seemed a bit lost, causing much laughter.
Both men demonstrated their exceptional vocal ranges, singing some of their hit tracks over the years. The two artists also held a sexy dance battle, as Wheesung danced to "Show Me Girl" while Hwanhee opted for BTS' "Blood, Sweat, and Tears", surprising the viewers.
