Adrian Monk is a fictional character portrayed by Tony Shalhoub and the protagonist of the USA Network television series Monk. He is a renowned former homicide detective for the San Francisco Police Department. Monk suffers from severe obsessive-compulsive disorder and multiple phobias, all of which intensified after the murder of his wife Trudy, resulting in his suspension from the department. He works as a private police homicide consultant and undergoes therapy with the ultimate goal of overcoming his grief, taking control of his phobias and disorder, and being reinstated as a police detective.

Series co-creator David Hoberman says that he based Monk partly on himself, and also on other fictional detectives, such as Lt. Columbo and Sherlock Holmes. Other actors considered for the role included Dave Foley, John Ritter, Henry Winkler, Stanley Tucci, Alfred Molina and Michael Richards. The network eventually chose Shalhoub because they felt he could "bring the humor and passion of Monk to life." Stanley Tucci and Alfred Molina had guest appearances on Monk, with Tucci appearing in season 5 episode "Mr. Monk and the Actor", and Molina appearing in season 6 episode "Mr. Monk and the Naked Man".

Robert "Rocky" Balboa, Sr. is a fictional character and the protagonist of the Rocky series from 1976 to 2006. During the series, he wins the Heavyweight Championship of the World twice. He was portrayed by Sylvester Stallone.

Robert Balboa was born on April 6, 1946. He was the only child to a Roman Catholic Italian-American family. It was revealed in Rocky II that Rocky's black trunks with gold trim were the colors of his high school that he never graduated from. During the scene in which Rocky takes Adrianna "Adrian" Pennino skating on Thanksgiving, he tells her "Yeah -- My ol' man who was never the sharpest told me -- I weren't born with much brain so I better use my body." This encouraged him to take up boxing. He trained very hard so he could grow up to be like his idol Rocky Marciano. Unable to live on the small pay of club fights, and being unable to find work anywhere else, Rocky got a job as a collector for Tony Gazzo, the local loan shark, just to make ends meet. By late 1975, Rocky had fought in 64 fights, winning 44 (38 KO'S) and losing 20. Rocky was proud that he never had his nose broken in a professional fight. His nickname is "The Italian Stallion," spawning from his Italian-American heritage.
