Throughout the massacre in the library, they ordered everybody to get up, saying that the library was going to explode. They stated how long they had been waiting for this, and seemed to be enjoying themselves, shouting things like, "Yahoo!" after shooting. While ordering the jocks to stand up, one of the two said, "Anybody with a white hat or a sports emblem on it is dead." Wearing a white baseball cap at Columbine was a tradition among sports team members. Nobody stood up, and several students tried to hide their white hats.
