Can anyone help me find a show that Heechul was in?

I really don't remember how this show was called or how I found it, and for some reason I can't find it in my youtube favorites or anywhere else, so I guess I just didn't save it ;;
Anyway, it was something like this:
The MCs "kidnapped" Heechul and "tested" him to see if he's the real Kim Heechul. They asked him about 100 or more questions that he answered to on his CYWORLD, and he got all the answers wrong XD and they asked him to say all of Super Junior members and he couldn't tell... And I remember that there were other members too, I don't remember who but I know for sure that Shindong was there and they asked Heechul what is Shindong's birthday, and he didn't know and Shindong said that it acutally means that it IS Heechul because Heechul doesn't know when's his birthday...
Anyway, if anyone knows what I'm talking about and can tell me what's the name of the show or even give me a link to this, I'll be really greatful~
