From The Museum of Hoaxes:
Dick Tuck was a legendary political hoaxer who made a career out of making life miserable for Richard Nixon.
In 1950 both Nixon and Tuck were near the start of their careers. Nixon was running for a California senate seat against democratic opponent Helen Gagahan Douglas, and Tuck was working for Douglas’s campaign.
Nixon was running an extremely dirty campaign, making every effort to portray his opponent as a communist-sympathizer. This red-bashing had already worked successfully for him in a 1946 congressional race against the democrat Jerry Voorhis, and had propelled him to national fame as a member of the House Committee on Un-American Activities. Tuck decided that he would undermine Nixon by getting himself hired as a campaign worker in Nixon’s campaign, where he would secretly operate as a mole for Douglas.
As a campaign worker for Nixon, Tuck was responsible for organizing campaign rallies. He organized one such rally at UC Santa Barbara, and he booked the largest auditorium possible. However, he purposefully booked it on a day that few students would be able to attend, and then he barely publicized it at all. Therefore, when Nixon showed up to speak there were only 40 students waiting to hear him in a 4000 seat auditorium. Tuck got up on the stage to introduce Nixon and proceeded to deliver a long, rambling monologue in which he made frequent references to Nixon’s cut-throat, red-bashing campaign tactics against Jerry Voorhis. Finally he announced that Nixon would now speak about the International Monetary Fund. Nixon, of course, had not planned to speak about the IMF. Therefore, when he got up to the podium he was momentarily speechless.
