<P> "Go ahead, make my day" is a catchphrase written by Charles B. Pierce and spoken by the character Harry Callahan from the 1983 film Sudden Impact . In 2005, it was chosen as No. 6 on the American Film Institute list, AFI's 100 Years...100 Movie Quotes . </P> <P> The phrase "go ahead, make my day" was written by Charles B. Pierce, an independent filmmaker who is credited with "story by" in the film Sudden Impact . The actual origins of the phrase came from Pierce's father Mack, who used to tell him as a child, "Just let me come home one more day, without you mowing that lawn, son just go ahead...make my day". </P> <P> At the beginning of the movie, Harry Callahan (Clint Eastwood) goes into a diner for a morning cup of coffee where he discovers a robbery in progress . He kills all but one of the robbers in a shootout . However, the surviving robber grabs the fleeing waitress Loretta (Mara Corday), holds his gun to her head, and threatens to shoot . Instead of backing off, Harry points his . 44 Magnum revolver into the man's face and dares him to shoot, saying with clenched teeth and in his characteristic rough grumble, "Go ahead, make my day," meaning that if the robber attempts to harm Loretta in any way, Harry would be happy to dispatch the robber . At the end of the film, Harry, again, says "Come on, make my day" just before shooting Mick the rapist, who aims his stolen shotgun at Harry's lover, Jennifer Spencer . </P> <P> When speaking out against taxes at the 1985 American Business Conference, President Ronald Reagan, himself a former actor, stated "I have my veto pen drawn and ready for any tax increase that Congress might even think of sending up .

Pierce reacted to this saying that his proudest moment was telling his father, "Tonight the President Ronald Reagan of the United States just quoted you ." </P>
