What part did toi like from shinee? How did toi discover SHINee hello baby?

i was watching vidéos on Youtube about Key and minho's b-day and there were commentaires that a dit "I wish they were able to celebrate with yooguen :( i miss hello baby" something like that and i was like hello baby 0-0 what's that? Then i watched some vidéos of them in variety shows and on the high rated commentaires it a dit i wish they get to be on plus shows like Hello baby :]

I was on Youtube and saw a video of a little boy s’embrasser Taemin, and another one about the same little boy hitting his head on Taemin's butt.

I started to get curious, because in the comments, they mentioned Hello Baby, and Yoogeun, and eventually, I started to watch it. One of the best days of my life.
