Eldrick Tont Woods (born December 30, 1975) better known as Tiger Woods, is an American professional golfer who is among the most successful golfers of all time. He has been one of the highest-paid athletes in the world for several years. Following an outstanding junior, college, and amateur career, Woods was 20 years old when he turned professional at the end of summer in 1996. By the end of April 1997, he had won three PGA Tour events in addition to his first major, the 1997 Masters.
When Woods first joined the PGA Tour in 1996, his long drives had a large impact on the world of golf. However, when he did not upgrade his equipment in the following years (insisting upon the use of True Temper Dynamic Gold steel-shafted clubs and smaller steel clubheads that promoted accuracy over distance), many opponents caught up to him. Phil Mickelson even made a joke in 2003 about Woods using "inferior equipment", which did not sit well with Nike, Titleist or Woods. During 2004, Woods finally upgraded his driver technology to a larger clubhead and graphite shaft, which, coupled with his clubhead speed, made him one of the Tour's lengthiest players off the tee once again.  Despite his power advantage, Woods has always focused on developing an excellent all-around game. Although in recent years he has typically been near the bottom of the Tour rankings in driving accuracy, his iron play is generally accurate, his recovery and bunker play is very strong, and his putting (especially under pressure) is possibly his greatest asset. He is largely responsible for a shift to higher standards of athleticism amongst professional golfers, and is known for utilizing more hours of practice than most.  From mid-1993 (while he was still an amateur) until 2004, Woods worked almost exclusively with leading swing coach Butch Harmon. From mid-1997, Harmon and Woods fashioned a major redevelopment of Woods' full swing, achieving greater consistency, better distance control, and better kinesiology. The changes began to pay off in 1999. From March 2004 to 2010, Woods was coached by Hank Haney, who worked on flattening his swing plane. Woods continued to win tournaments with Haney, but his driving accuracy dropped significantly. Haney resigned in May 2010 and was replaced by Sean Foley.  Fluff Cowan served as Woods' caddie from the start of his professional career until Tiger fired him in March 1999. He was replaced by Steve Williams, who became a close friend of Woods and is often credited with helping him with key shots and putts. In June 2011, Woods fired Williams and replaced him with friend Bryon Bell on an interim basis. Joe LaCava, a former caddie of both Fred Couples and Dustin Johnson, was hired by Woods shortly after and has remained Woods' caddie since then, but he has seen very limited work.

Brown was born in Mineola, a small segregated town in east Texas marked by racial tensions, to Minnie Collins Boyd and Lewis Brown. Brown was the fourth of five children. During Brown's childhood, mob violence periodically erupted in Mineola, keeping African- Americans from voting. His first job was a shoeshine boy in a whites-only barber shop.
As Mayor of San Francisco, Brown was often portrayed mockingly but affectionately by political cartoonists and columnists as a vain emperor, presiding in a robe and crown over the inconsequential kingdom of San Francisco. He enjoyed the attention this brought to his personal life, disarming friends and critics with humor that directed attention away from the policy agendas he was pursuing.  Brown's flamboyant style made him so well known as the consummate politician that when an actor playing a party politician in 1990's The Godfather Part III did not understand director Francis Ford Coppola's instruction to model his character after Brown, Coppola fired the actor and hired Brown himself to play the role. Brown later appeared in 2000's Just One Night as a judge. He also played himself in two Disney films, George of the Jungle and The Princess Diaries, and the 2003 Universal release Hulk as the mayor of San Francisco. He appeared as himself, alongside Geraldo Rivera, in an episode of Nash Bridges. He also made a cameo appearance in the 1984 Jefferson Starship music video "Layin' It on the Line" (depicting a futuristic 1988 presidential campaign).  Brown was criticized in 1996 for his comments that 49ers backup quarterback Elvis Grbac was "an embarrassment to humankind." He was criticized in 1997 for responding to Golden State Warriors player Latrell Sprewell choking his coach P. J. Carlesimo by saying, "his boss may have needed choking."  In 1998, Brown contacted the Japanese television cooking competition Iron Chef, suggesting San Franciscan Chef Ron Siegel to battle one of the Iron Chefs. Brown appeared on the telecast himself, enthusiastically promoting the Chef. Siegel won the battle, in a rare clean sweep against Iron Chef Hiroyuki Sakai.  Brown remained neutral throughout the 2008 presidential campaign. Brown has been working in recent years as a radio talk show host and as a pundit on local and national political television shows and is seen as attempting to build credibility by abstaining from endorsing candidates for office. "I've never been high on endorsements," Brown said. "When you get one, all it does is keep the other guy from getting one. Really, what did getting John Kerry's endorsement do to help Barack Obama?"
