Conan Christopher O’Brien is born in Brookline, Massachusetts to an Irish-Catholic family. His parents are doctor and Harvard professor Thomas O’Brien and lawyer Ruth O’Brien (née Reardon). The third of six children, he has three brothers and two sisters. His penchant for comedy starts as early as the third grade, where he does Charlie Chaplin impersonations and cracks jokes to make his family laugh. He also takes an interest in tap dancing.
It starts with the family. I’m from a large Irish-Catholic family and trying, the benchmark, for me, is trying to make my dad laugh or trying to make my brothers laugh at the table when we were having meals together.
