Rollen Fredrick Stewart (born February 23, 1944), also known as Rock'n Rollen and Rainbow Man, is a man who was a fixture in American sports culture best known for wearing a rainbow-colored afro-style wig and, later, holding up signs reading "John 3:16" at stadium sporting events around the United States and overseas in the 1970s and 1980s.
Stewart became a born-again Christian, and was determined to "get the message out" via television. His first major appearance was at the 1977 NBA Finals; by the time of the 1979 MLB All-Star Game, broadcasters actively tried to avoid showing him. He "appeared behind NFL goal posts, near Olympic medal stands, and even at the Augusta National Golf Club." At the 1982 Indianapolis 500, he was behind the pits of race winner Gordon Johncock. Stewart would strategically position himself for key shots of plays or athletes. Stewart's fame led to a Budweiser beer commercial and a Saturday Night Live parody sketch, where he was portrayed by Christopher Walken.
Stewart was briefly jailed by Moscow police at the 1980 Summer Olympics. In the late 1980s, he began a string of stink bomb attacks. Targets included Robert Schuller's Crystal Cathedral, the Orange County Register, the Trinity Broadcasting Network, and a Christian bookstore. The stated intent of an attempted attack at the American Music Awards was to show the public that "God thinks this stinks."
