The beautiful ladies of SNSD/Girls' Generation have been driving fanboys wild with concept and video teasers for their 3rd mini album track, "? / Hoot." �But now, fan girls have a reason to go crazy as well, because Choi Si Won makes a guest appearance in the music video. Check it out! The MV was certainly well worth the wait! On a side note, people have been asking about the cowboy/cowgirl western theme, and SM Entertainment is either very clever, or it was a complete coincidence, but...if you look closely at the hangul for "Hoot", you should be able to notice that it looks like a person with a cowboy hat on. Anyway, stay tuned to allkpop for their comeback performance on October 29th's Music Bank!
