Abbie Hoffman and Jerry Rubin became the most famous Yippies—and bestselling authors—in part due to publicity surrounding the five-month Chicago Seven Conspiracy trial of 1969. They both used the phrase "ideology is a brain disease" to separate the Yippies from mainstream political parties that played the game by the rules. Hoffman and Rubin were arguably the most colorful of the seven defendants accused of criminal conspiracy and inciting to riot at the August 1968 Democratic National Convention. Hoffman and Rubin used the trial as a platform for Yippie antics—at one point, they showed up in court attired in judicial robes.
