What happens

A blonde woman with a grey-streaked beehive-like hairdo and a blue dress with a tan patch, wearing bracelets and blue heels, first stands glaring against a purple wall, then crouches to scoop up a handful of snow from the floor. Lisa, the girl with star-shaped spiky hair in a red dress and pearl necklace, stands in a snowy gymnasium decorated with garland and a disco ball, then turns as the woman stumbles and runs past with the snowball in her raised hand. In the wider crowded dance hall, Ralph in a black tuxedo sits in the foreground holding a small red box, while Milhouse lies sprawled in the snow in a white suit and other partygoers mill about under falling snow.
