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

I really don't remember how this Zeigen was called oder how I found it, and for some reason I can't find it in my Youtube Favoriten oder 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 oder Mehr Fragen that he answered to on his CYWORLD, and he got all the Antwort 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 sagte 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 Zeigen oder even give me a link to this, I'll be really greatful~
