If you use chrome, there is nothing easier than getting adblock. I love it. Fuck ads.
Here is a video with two episodes of Strong heart in it, The first is Yuris story and the second sunny. Both are similar but different events Quite funny. Jessica is mentioned in both stories but she's only present during the story telling in the second.
Also of the people you see the camera pan to at times to see their reaction, from the first story there is 1 and from the second there are 2 Kara members, one is Hara so see if you can pick her out! Also you see Leeteuk laugh and he has the best laughing facial expression ever.
This one I'll embed because it's Gangnam style.
The first guy whom you see walking slowly, is an awesome comedian and member of running man but also he's the guy in the yellow suit in the Gangnam Style MV SNSD members are also in this video a fair bit because they have appeared on running man a few times. (Running man is a long running weekly variety show)
3:28 or maybe 4:24, okay, maybe at 8:33? Not sure. 3:58 is a Kara member, but I don't know who she might be? 5:57, another Kara member?
Hahaha! The part at 7:56 is hilarious! Damn, this show is amazing!
Second video is funny, I love the part where Sica just does her moves. Taeyeon's part too. xD
Just google adblock joy. Its in the chrome store for free.
