Some years in the future, SNSD is touring to promote their final album - Girls Generation Forever. The first concert is about to start. The girls are not yet on stage, it's dark in the arena, only a giant LED screen displaying "GIRLS GENERATION ∞" (you know, infinity ~ forever). Some fans are disgruntled because of them using the infinity symbol (∞) is bad taste, since it looks like the digit 8.
Suddenly, some technical problem causes interference with the main screen's signal, scrambling the image. The font is all messed up - the screwed up ∞ symbol now looks a bit like a horizontal digit 9! This unfortunate coincidence drives a lot of fans into a fit. There is much unrest in the crowd.

Under the cover of darkness, a single figure appears on the stage. Many people don't notice it because they are still fuming about the ∞ resembling a 9. The figure, in a very distinct nasal voice that a lot of people haven't heard in a while, says:

"Let's bring it back to 140 9"

8 other figures appear on the stage. The audience explodes.
