Are you enjoying f(x)'s new reality show 'f(x)=1cm'? Well, a ton of people are ever since it began online through Naver TVCast and YouKu. Everyone loves a 'molca', or hidden camera gag, and especially so if f(x) does it.

On the November 11 episode, f(x) transformed into high school students and surprised an entire classroom. This time around, in the 5th and 6th episodes, the girls surprise some (very lucky) rugby players! The girls hide out in the players locker room to shock the players, and all of the members and the players have a good time together.
