Yoo Jae-suk, wearing his yellow tuxedo and sunglasses as in the "Gangnam Style" video, rushes into an elevator, urgently needing to reach a bathroom, but Psy arrives and stalls the trip by pushing all the elevator floor buttons; he taunts the doubled-over Yoo with his dance. At a library, Psy farts in his hand—cupping it to contain and concentrate the flatus—and then, depicted in slow motion, delivers it in front of the face of a girl (Kim Hyun-Joo).Todd Gilchrist of MTV calls the farting prank a "stink-palm", while Susannah Butter of Evening Standard (London) calls it a "cupcake".
