[15] Martin withdrew from law school before the start of his final year, opting to pursue comedy over obtaining his Juris Doctor degree.

Starting in late 2005, he was credited as a contributor on The Daily Show, on which he appeared as the named "Senior Youth Correspondent" and hosted a segment called "Trendspotting".

He used this segment to talk about so-called hip trends among youth such as hookahs, wine, guerilla marketing and Xbox 360.

[22] On March 22, 2007, Martin made another appearance on The Daily Show, talking about the Viacom lawsuit against Google and YouTube.

[23] Before starting at The Daily Show, he was offered to audition for Saturday Night Live but turned it down due to the seven year commitment.

This album also features Saturday Night Live member Will Forte and stand-up comedian Leo Allen.

He also starred in the video for the Travis single "Selfish Jean", in which he wears multiple T-shirts with lyrics written on them.

In 2009, he hosted and starred in his own television show called Important Things With Demetri Martin on Comedy Central.

In the film Martin plays Elliot Tiber, a closeted gay artist who has given up his ambitions in the city to move upstate and help his old-world Jewish family run their Catskill Mountains motel.

Martin sold his movie concept Will to DreamWorks, and is expected to play a key supporting role.

He also signed a blind script deal with CBS in October 2010 to produce, write, and star in his own television series.

He uses one-liners and drawings on a "large pad", as well as accompanying his jokes with music on either guitar, harmonica, piano, keyboard, glockenspiel, toy bells, ukulele, or tambourine, sometimes all at once.

[34] He has cited comedian Steven Wright as an important influence (both use deadpan one-liners in their acts) as well as The Far Side cartoonist Gary Larson.

According to a July 2011 interview on the podcast WTF with Marc Maron, Martin had a short-lived marriage with a former high school classmate named Jen.

On June 1, 2012, Martin married his long-time partner Rachael Beame in Santa Monica, California.
