Patton Oswalt (born January 27, 1969) is an American stand-up comedian, writer, actor and voice actor known for roles such as Spencer Olchin in the popular sitcom The King of Queens, and voicing Remy from the film Ratatouille. Oswalt first began performing standup comedy in the late 1980s or early 1990s, by his own reckoning. After writing for MADtv and starring in his own 1996 comedy special for HBO, he went on to garner notable roles in films and television shows.

Oswalt's stand-up comedy covers topics ranging from pop culture frivolity such as comic book supervillains and 1980s glam metal to deeper social issues like American excess, materialism, foreign policy and religion. He also discusses his atheism in his stand-up. In 2004, Oswalt released a comedy album entitled Feelin' Kinda Patton and later that year a longer, unedited version of the same performance entitled 222 (Live & Uncut), both through the United Musicians collective, and a stand-up special, No Reason to Complain. He is also on a split EP called Patton vs. Alcohol vs. Zach vs. Patton with Zach Galifianakis and is featured on two Un-Cabaret compilations, "The Un & Only" and "The Good, the Bad and the Drugly". On July 10, 2007, Patton released his second CD Werewolves and Lollipops on Sub Pop records. On February 28, 2009, Oswalt recorded his third comedy album at the Lisner Auditorium at George Washington University in Washington D.C. It premiered on Comedy Central as Patton Oswalt: My Weakness is Strong on August 23, 2009, and was released on DVD August 25, 2009. Oswalt's latest album, Patton Oswalt: Finest Hour, was released on September 19, 2011. The extended and uncensored DVD of this special was released in April 2012, a few days after its television premiere on Comedy Central.
