I'm really sorry I don't have more information, but I only saw a small clip on youtube a few months ago and I can't find it again! I'll try to give as much as I can.

I think four members were there (Two of those were definitely Leeteuk and Heechul, but I can't remember which members the other two were)

They were sitting on stools, and a pretty waitress in a tight dress comes out and offers them water or something and then goes away. Then after, the host tells them the camera followed where their eyes went on a woman. Heechul looked at her legs, someone looked all over, one looked at the eyes (I think).

Does anybody know which show this was or have a link to the youtube clip?
