So there this thing goin around saying the lyrics for Beep Beep were composed by: Sooyoung, Yoona, and Sunny. The MV Directed by Tiffany and Jessica. Cheorography was by Taeyeon, Yuri, Hyoyeon, and Seohyun. 

The thing that caught my attention was MV Directed by Tiffany and Jessica...and this is what goes on in my head thinking how the meeting went down:

Tiffany: So Jessica and I can direct the video?

CEO: Yes...

Tiffany: We can design the MV?

Jessica and the other:...Oh no..

CEO: -hesitant- Yes.

Tiffany: -eyes light up in gleam- CEO do you by any chance know a place with a large pink telephone!?

Rest of SNSD: Pink everywhere...

Sica: Tiff, chill with the pink.

Tiffany: Pink everywhere~ Pink everywhere Jess! TaeTae! Pink!

Rest of SNSD (minus Sica and Tiff): CEO do you really trust her!

CEO: -hesitant smile- Director Hwang hwaiting!

Tiffany: PINK!
