- The Cameo: Although not part of the show proper, the KBS-uploaded episodes on YouTube retain the show's ending credit sequence. KBS would frequently air clips from music videos in this time, leading to appearances from artists such as Crayon Pop, FTIsland, and many others.
- They Changed It, Now It Sucks!: For several reasons, the second season never experienced the success or warm reception that the first experienced. This started to change after the show found an identity and purposeful goal in the Invincible B&B, but by then the show's days were numbered and it was cancelled after 46 episodes.
- The Cutie: Sunny in both seasons
- Jiyoung and Suzy in Season 2, especially after Sunny left.
