Girls' Generation's Himnaera Him!, is a South Korean television reality show starring the popular Korean girl group Girls' Generation. The show and cast operated under the goal of being the Republic of Korea's cheering squad, with the intention of cheering up the citizens during an economic slump.
It was announced that a new show starring the popular group titled 'Himnaera-Him!' or 'Cheer Up!' was chosen to take the timeslot, and began airing the week after the last episode of Horror Movie Factory. However, as the group released their new EP 'Tell Me Your Wish (Genie)' and became busier with promotions, the show was discontinued after only 2 episodes when the group's management decided to have them leave the MBC Sunday Sunday Night segment. On the broadcast date of the final episode of Cheer Up!, it was announced the group would be starring in a new reality show on KBS rather than MBC, titled Girls' Generation's Hello Baby, for which the group received a much more positive reaction than anything previously done on MBC's Sunday Sunday Night segment.
