Dennis Leary - As*hole

Denis Colin Leary (born August 18, 1957) is a Golden Globe- and Emmy Award-nominated American actor, comedian, writer and director. He is known for his often angry comedic style, and his chain smoking. As of 2009, Leary is the star and co-creator of the television show Rescue Me.

Leary was born in Worcester, Massachusetts, the son of Irish Catholic immigrants. His mother, Nora, was a maid. His father, John Leary (deceased), was an auto mechanic. Since both of his parents are from Killarney, County Kerry, Ireland, Leary holds both Irish and American citizenship. He graduated from Saint Peter-Marian High School, in Worcester. Through marriage, Leary is a distant cousin of talk show host Conan O'Brien and has jokingly said on Late Night with Conan O'Brien that, "All Irish people are related." His name is often misspelled as "Dennis" instead of the correct "Denis."
