Taeyeon: *Explaining how the height differences in the group work out*
Sooyoung: *Leans over and mutters something to the MC*
MC: She says you wore insoles!
Taeyeon: *Sputtering, to Sooyoung* WILL YOU PLEASE BE QUIET?
To clarify: What starts out as a simple airing of grievances between the tall and the short members quickly descends into a massive free-for-all where each members annoying habits are exposed and ridiculed. Even the MC's (who are supposed to keep some kind of order and structure to the show) are effectively relegated to the sideline while the girls duke it out amongst themselves. And this keeps going for a full 35 minutes. You can watch it here. (at least until Youtube removes it.)
Also qualifies as a Crowning Moment of Awesome for Seohyun. At one point the other members gang up on her commenting on her naivety and her dislike of boys. Seohyun not only has an answer for every single comment she also remains completely calm during the whole process never once losing her cool.
Some of the videos (VTRs/VRCs) which serve as intermission numbers between songs during their concerts count as this. Trynottogiggle.
Taeyeon's Big Entrance on Running Man. The other cast members on the show got paired up with old men, except for Gwangsoo, who can't find his partner.note It's Taeyeon. His partner is Taeyeon.
Now, cue a speedboat suddenly appearing on the beach's horizon, with the song "Twinkle" blasting from speakers on said boat. On the speedboat, a woman appears, doing some kind of impromptu concert (and drinking flower tea).note It's Taeyeon.
Courtesy of an Inkigayo fan account from 01/06/13:
Jessica threw her hat to where the fans were, and she got surprised when a fan got hit. When the fans said they were okay, she got the hat, looked over it, and asked, “Hat, are you okay?”
Anytime Sunny and Taeyeon are being teased◊ about their height.
Poor Sooyoung! She's lamenting not getting very many lines, so Sunny reaches out to pat her on the arm◊ and comfort her... then suddenly snatches her hand back. What happened? She pricked her hand on the spikes on Sooyoung's jacket! "Fashion is pain" indeed◊.
Some of the faces◊ Taeyeon makes◊ during live performances definitely count.
A lot of their live antics◊ count - they're just having so much fun up there you can't help but laugh along!
Their engrish skills (but be wary that they've improved nowadays).
Sooyoung's... improvised version of the arrow◊ dance from "Hoot".
Jessica's comment about "Don't run, however late you are. It just makes you tired and hot, and that's no fun!"
Tiffany, Sooyoung, Jessica and Yuri were giving an interview and when the interviewer made a comment along the lines of "pretty kids are always nice", Tiffany zinged◊ Jessica with a sweetly spoken "You must not be pretty, then!"
SNSD does the limbo. Noteworthy moments include Sooyoung and one of the hosts dancing together very intently - and then the host's wife chews him out, Hyoyeon managing to do a dance routine to the national exercise music, and Sunny being Sunny.
