I didn't see this thread before.
I've got a bunch, but here's a few for now.
- Sunny and Taeyeon'd dads were in rock bands when they were younger.
- Hyoyeon is the funniest member and an amazing dancer off camera but she freezes up on shows.
- Yoona was a huge S.E.S. fangirl and was inspired to try out after watching them.
- Hyoyeon studied in China along with Siwon from Super Junior for a year.
- Yuri's friend saw an add for the best selection contest (where she was coasted) and made her go.
- They used to practice till 3am and would bring sleeping bags to get some sleep before school in the morning.
- Taeyeon has said her ideal man is Vegeta.
- A few of them wore heels for the first time during their showcases.
Sunny, Seohyun, Sooyoung, and Tiffany all attend the same church that MC Mong goes to.
I think a lot of famous people go to that same one. Tim, Brian Joo, Siwon ect. The Blue go there as well. I'm guessing that's how Sooyoung and Tiffany ended up doing a song with them.
