While information on Andy Richter's specific handedness is not widely documented, he stands as a celebrated figure in comedy, primarily known for his role as Conan O'Brien's sidekick. Born on October 28, 1966, in Grand Rapids, Michigan, Paul Andrew "Andy" Richter was raised in Yorkville, Illinois. He hails from a family with a background in the arts; his mother, Glenda Swanson Richter, is a kitchen cabinet designer, and his father, Laurence R. Richter, taught Russian at Purdue University. Andy’s upbringing fostered a creative environment that would later shape his comedic sensibilities.

Richter's journey into comedy began during his time at Columbia College Chicago, where he studied film and video. However, his passion for improvisation led him to drop out and pursue comedy full-time. He joined the Annoyance Theater and later moved to Chicago's renowned Second City, where he honed his improv skills and developed his unique comedic style. It was during his time at Second City that he caught the attention of Conan O'Brien, who was then preparing to launch his late-night talk show.

In 1993, Andy Richter joined 'Late Night with Conan O'Brien' as a writer and sidekick. His quirky characters, absurd sketches, and quick-witted banter quickly made him a fan favorite. Richter's comedic timing and ability to play off O'Brien's humor proved to be a winning combination, contributing significantly to the show's success. He remained a key member of the 'Late Night' team for seven years, leaving in 2000 to pursue other opportunities.

Following his departure from 'Late Night,' Richter ventured into acting, starring in several sitcoms, including 'Andy Richter Controls the Universe' and 'Quintuplets.' He also made numerous guest appearances on popular television shows and lent his voice to animated series such as 'Madagascar' and 'Bob's Burgers.' In 2009, Richter reunited with Conan O'Brien as the announcer and writer for 'The Tonight Show with Conan O'Brien' and later 'Conan' on TBS. His enduring partnership with O'Brien solidifies his legacy as one of the most beloved sidekicks in late-night television history.
