The section can hold approximately 1,200 occupants. The name became widely known as Mike Krzyzewski's program. It became one of the best in the country. In an article about the Crazies published in 2007, Al Featherston stated, "Duke's crowd may or may not be the best student section… but it is the standard by which all others are measured." Some other colleges and universities have used the Crazies as a model for their own cheering sections at basketball games, such as Harvard University and Indiana University, both of which recently printed a run of Crimson Crazies T-shirts. Over the years, some have noted that the Crazies have calmed down due to restrictions, such as not being able to throw things onto the court.
Once during a game, a television network had to turn off the sound because the Crazies were chanting about one of the sponsors. Pranks included tossing bags of uncooked noodles during warmups at Georgia Tech's Craig Neal, who was 6'5" and weighed 160 pounds, throwing Twinkies at Georgia Tech's Dennis Scott because he was overweight, tossing pizza boxes as North Carolina State University's Lorenzo Charles walked on court after being caught stealing pizzas a few weeks prior to the game. Chris Washburn had records thrown at him after being charged with stealing a stereo.
Another famous instance of the Crazies' antics occurred in a Duke/UNC matchup on February 9, 2005. It was Roy Williams' first visit to Cameron Indoor as UNC head coach after formerly leaving his head coaching position at the University of Kansas. The Cameron Crazies used this knowledge and greeted the visiting Tar Heels in creative fashion. Some Duke fans dressed up as characters from The Wizard of Oz and prepared a yellow brick road for the Tar Heels to communicate that Williams was "not in Kansas anymore".
One of their most famous chants occurs whenever an opposing player fouls out. As the player goes back to his bench, the Crazies mockingly wave at him and chant "Aaaaaah ..." When he sits down, they yell, "See ya!" Several players have been known to keep standing for long periods—as long as the remainder of the game—to keep from hearing "See ya!"
Criticism
In the past, the cheers and chanting have offended some coaches and fans, including Coach Krzyzewski, who in 1994 publicly asked the students to cheer for their team, not against the opposing team.
