FBI Special Agent Dale B. Cooper is a character from the television series Twin Peaks, created by David Lynch and Mark Frost. He is the lead protagonist of the series and also briefly appears in the prequel film Twin Peaks: Fire Walk with Me. Cooper (played by Kyle MacLachlan) is an FBI agent who arrives in Twin Peaks to investigate the brutal murder of the popular high-school student, Laura Palmer, and falls in love with Twin Peaks and gains a great deal of acceptance within a tight knit community. He displays an array of quirky mannerisms such as giving a 'thumbs up' when satisfied, sage-like sayings, distinct sense of humor, along with his love for a good cherry pie and a "damn fine cup of coffee". One of his most popular habits is recording spoken-word tapes to a mysterious woman called 'Diane' into his dictaphone that he always carries with him, that often contain everyday observations and thoughts on his current case.
