Pines are trees in the genus Pinus ( /ˈpaɪnəs/), in the family Pinaceae. They make up the monotypic subfamily Pinoideae. There are about 115 species of pine, although different authorities accept between 105 and 125 species.

The modern English name pine derives from Latin pinus by way of French pin; similar names are used in other Romance languages. In the past (pre-19th century) they were often known as fir, from Old Norse fyrre, by way of Middle English firre. The Old Norse name is still used for pines in some modern north European languages, in Danish, fyr, in Norwegian fura/fure/furu, Swedish, fura/furu, and Föhre in German, but in modern English, fir is now restricted to Fir (Abies) and Douglas-fir (Pseudotsuga).

Pines are divided into three subgenera, based on cone, seed and leaf characters:

Pines are native to most of the Northern Hemisphere. In Eurasia, they range from the Canary Islands, Iberian Peninsula and Scotland east to the Russian Far East, and in the Philippines, north to just over 70°N in Norway, Finland and Sweden (Scots Pine) and eastern Siberia (Siberian Dwarf Pine), and south to northernmost Africa, the Himalaya and Southeast Asia, with one species (Sumatran Pine) just crossing the Equator in Sumatra to 2°S. In North America, they range from 66°N in Canada (Jack Pine and Red Pine), south to 12°N in Nicaragua (Caribbean Pine). Pines have been introduced in subtropical and temperate portions of the Southern Hemisphere, including Chile, Brazil, South Africa, Tanzania, Australia, Argentina and New Zealand, where they are grown widely as a source of timber. A number of these introduced species have become invasive, threatening native ecosystems.

John R. "Johnny" Cash (February 26, 1932 – September 12, 2003), was an American singer-songwriter, actor, and author, who has been called one of the most influential musicians of the 20th century. Although he is primarily remembered as a country music icon, his songs and sound spanned many other genres including rockabilly and rock and roll—especially early in his career—as well as blues, folk, and gospel. This crossover appeal led to Cash being inducted in the Country Music Hall of Fame, the Rock and Roll Hall of Fame, and Gospel Music Hall of Fame.

Cash was known for his deep, distinctive bass-baritone voice; for the "boom-chicka-boom" sound of his Tennessee Three backing band; for his rebelliousness, coupled with an increasingly somber and humble demeanor; for providing free concerts inside prison walls; and for his dark performance clothing, which earned him the nickname "The Man in Black". He traditionally started his concerts by saying, "Hello, I'm Johnny Cash." and usually following it up with his standard "Folsom Prison Blues".

Robert Norman "Bob" Ross (October 29, 1942 – July 4, 1995) was an American painter, art instructor, and television host. He is best known as the creator and host of The Joy of Painting, a television program that ran on PBS in the United States.

Ross was born in Daytona Beach, Florida, and attended school until the ninth grade. Raised in Orlando, Florida, Ross enlisted in the U.S. Air Force at age 18 and was living in Florida early in his military career when the Air Force transferred him to Eielson AFB (in Alaska), where he first saw the snow and mountains that later became recurring themes in his artwork; he developed his quick-painting technique in order to be able to create art for sale in brief daily work breaks. Having held military positions that required him to be, in his own words, "mean" and "tough," "the guy who makes you scrub the latrine, the guy who makes you make your bed, the guy who screams at you for being late to work," Ross decided that if he ever moved on from the military, "it wasn't going to be that way any more," "vowing never to scream again". Ross discovered after beginning his sideline in painting that he was soon able to earn more from selling his work than from his Air Force position. After leaving the Air Force, he studied with Bill Alexander before becoming famous worldwide with his own television program, The Joy of Painting.
