that's one of the iconic jpop artist 工藤 静香(Kudo Shizuka) back in the late 80's along with Noriko Sakai etc

Well, I've already seen the video and it seems it is Ayumi herself who first tells about that hip cracking thing about Kudo Shizuka, so she still remembered. She still did surprise though, as I did, cause when I saw that Ayuready one the noise wasn't so strong, now it gave me the creeps :dead2

Ohh, that would explain it, then. Thanks for the info!
I don't know enough Japanese, so I didn't realize Ayu was really the one explaining everything. All I could was Ayu was talking about hips.

oh i remember this episode!!!!! hey hey hey, is one of those shows where i dont feel stupid laughing alone. i dun remember her name, but it freaked the hell outta me when she cracked her hip. this makes me want to procrastinate doing work and watch this episode again. hAHa.

Yup, Ayu didn't fake her astonishment. She knew about it before hand. But you do realise that there are certain things that you'll still be shocked over and over again! I have friends who can do really weird things like have their eyes both go different directions and it never fails to freak me out. This is just one of those things for Ayu.
