Born on the Fourth of July Easter Egg - Historic Cameo

It has been awhile since I saw the movie, but it's near the end of the movie when the main character is being wheeled into the stage for him to deliver a speech or something.

Amongst the people crowding around him is legendary sixties hippy, yippie (yes it is spelled correctly) and all around great guy Abbie Hoffman in a cameo role. He doesn't say anything but it's definitely him, the credits even mention him. Abbie Hoffman devoted a large portion of his life to upsetting the country enough to stop the Vietnam War.
