David Andrew "Andy" Samberg (born August 18, 1978) is an American actor, comedian, rapper, and writer best known as a member of the comedy group The Lonely Island and as a cast member on Saturday Night Live from 2005 to 2012. On Saturday Night Live, he and The Lonely Island have been credited with popularizing the Emmy-winning SNL Digital Shorts, the comical short films and music videos starring Samberg and other members of the SNL cast.

Samberg was born in Mill Valley California, the son of Joe Samberg, a photographer, and Margi (née Marrow), an elementary school teacher who taught at Old Mill School. Samberg also has two sisters, Johanna and Darrow. He was raised in a Jewish household. His maternal grandfather, Alfred J. Marrow, served as the executive chair of the American Jewish Congress, although Samberg describes himself as "not particularly religious." Samberg discovered Saturday Night Live as a child while sneaking past his parents to watch professional wrestling on television. He became "obsessed" with the show, and his devotion to comedy became frustrating to teachers who felt he was unfocused on his schoolwork.

As a child, Jackman liked the outdoors, spending a lot of time at the beach and on camping trips and vacations all over Australia.

Because I'd been on a plane and there was food on board, I presumed there was a chef. I thought that would be an ideal job."

Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known as one of four co-founders of the social networking site Facebook, of which he is chairman and chief executive.

Zuckerberg was born and raised in a Jewish household in New York state. While still in middle school in his early teens, he took up writing software programs as a hobby, beginning with BASIC, with help from his father. His father then hired a tutor to help his son develop his programming skills further. Zuckerberg's enjoyment in writing programs led him to developing computer games, writing a music player, and setting up a primitive home network he called "ZuckNet." His private tutor calls him a "prodigy." In high school he excelled in classic literature and science, while becoming proficient in four other languages. He was also captain of the school's fencing team.

He later enrolled in Harvard, majoring in computer science and sociology. In his sophomore year he wrote a program called Facemash as a "fun" project, letting students on the college's network vote on other students' photo attractiveness. It was shut down within days, but would become a template for his writing Facebook, a program he launched from his dormitory room. With the help of friends, including roommate Dustin Moskovitz, Facebook went national on other campuses, and they moved to Palo Alto, California. By 2010, the site had an estimated 500 million users worldwide. Zuckerberg and Facebook have since been involved in various legal disputes initiated by others who have claimed a share of the company's profits due to their help in setting it up. Zuckerberg is the largest individual shareholder with 28.4 percent of the common stock and controls 56.9 percent of the voting power. As of 2012^[update], his personal wealth was estimated at more than $19.1 billion, making him one of the world's youngest billionaires. Zuckerberg is one of the 30 richest people on Earth.
