In 1973 , Yippies marched on the Manhattan home of Watergate conspirator John Mitchell : ... five hundred die-hard Yippies staged one last march on the Mitchell home , no longer the Watergate but a grand apartment building on Manhattan 's Fifth Avenue . " Free Martha Mitchell ! " they chanted . " Fuck John ! " When the Mitchells finally appeared at the window to see what all the commotion was about , the stoners cherished their last " eye-to-eyeball confrontation with Mr. Law 'n' Order . " To commemorate the moment , they placed a giant marijuana joint on the Mitchells ' doorstep . Yippies regularly protested at US presidential inaugurations , with a particularly strong presence at the 1973 inauguration of Richard Nixon . Yippies also demonstrated at the 1980 Republican National Convention in Detroit , as well as the subsequent 1984 Republican National Convention in Dallas , where 99 Yippies were arrested : Yippies organized marijuana " smoke-ins " across North America through the 1970s and into the 1980s . The first YIP smoke-in was attended by 25,000 in Washington , D.C. on July 4 , 1970 . There was a culture clash when many of the hippie protesters strolled en masse into the nearby " Honor America Day " festivities with Billy Graham and Bob Hope
