From Oh! My School Episode 17:

Simon D: I'm a Beast Fan. Y' know, mystery, mystery oh! mystery, mystery, oh! mystery, mystery, oh!

Yoseob (BEAST): Aish, you're like a human CD player. Except you missed a small detail.

Simon D: ?

Yoseob: It's not mystery, mystery, oh! It's Girl. Scene. Love. So it's mystery, mystery, girl! mystery, mystery, scene. mystery, mystery, love.

Everyone: ooohhhh.

Kikwang (BEAST): Wait! How do you know something I don't?

Yoseob: (dramatically stands up) Because I recorded that part! I'm the main vocalist!

Kikwang: (Stands up too) Well I'm the main dancer!

Simon D: And Kikwang's more popular than you.

Host: Hey, Yoseob's popular too!

Yoseob: Yeah! I'm the cutest!

Simon D: Doojoon's in 2nd place for that (after Kikwang).

Yoseob: Then I'm 3rd! I'll be 3rd!! So there! 3rd place is mine! (≧o≦)

Yoseon (T-ara): (Defends Yoseob) Yah! Do you know how hard it is to stay up all night recording the chorus?!

Simon D: We don't want to know such pain.

Hyosung (Secret): (Defends Kikwang) Do you know how hard it is to teach dance moves all the time?
