Attell's first appearance on television was in 1988 on
VH1's
Stand-Up Spotlight, which also featured early appearances by
Lewis Black,
Margaret Cho,
Jeff Garlin,
Jay Mohr and
Wanda Sykes. On November 23, 1993, he made his first appearance on
Late Show with David Letterman. The appearance was seen by
Saturday Night Live creator
Lorne Michaels, who then recruited Attell to be a writer and occasional performer on
SNL. Attell can be seen behind
Chris Farley during the "
Rudy Giuliani Inauguration" sketch. Attell worked on the show for the 1993–94 season. In 1995, Attell was featured on two
HBO specials alongside up-and-comers
Louis C.K. and
Dave Chappelle. In 2003, Attell began appearing on
Tough Crowd with Colin Quinn. The show featured many of the performers he works with at the New York City comedy club the
Comedy Cellar and is based on the conversations they would have off-stage at the Olive Tree Cafe, the restaurant above the club. Attell appeared on Comedy Central's
Last Laugh in 2007. His first one-hour special,
Dave Attell: Captain Miserable aired December 8, 2007, on HBO. In 2008, Attell began hosting
The Gong Show with Dave Attell for
Comedy Central. Like the
1970s version, the show had a rotating panel of celebrity judges grading unusual acts. In May 2008, Attell announced a casting call on his MySpace page for Comedy Central's relaunch of
The Gong Show. Attell was host, along with Greg Fitzsimmons serving as head writer on the series. However,
The Gong Show with Dave Attell aired only from July to September 2008. In January 2010, he co-hosted the
AVN Awards show, along with porn actresses
Kirsten Price and
Kayden Kross; and again in 2012 with co-hostesses
Sunny Leone and
Bree Olson. Attell returned to television on Showtime beginning October 20, 2011, in ''
Dave's Old Porn'', a TV series in which Attell views and jokes about retro 1970s and 1980s pornographic films with different guest comedians. Typically, during a given show, Attell and his guest view clips that give an overview of a particular retro porn star's career. Near the end of the show, that particular actor appears and also comments on clips from some of their films. In April 2014, Comedy Central premiered
Comedy Underground with Dave Attell, a late-night stand-up comedy show taped live in New York. His comedy special
Dave Attell: Road Work aired 2014 on
Comedy Central. In 2018, he toured with
Jeff Ross on the Bumping Mics Tour. Over the last three days of the tour they taped a three-part documentary series,
Bumping Mics with Jeff Ross & Dave Attell for
Netflix. Interspersed footage showcases the duo's interactions both off-stage and on as they return to the
Comedy Cellar, where a spontaneous first performance marked the birth of their ensemble act. In 2024, Attell released the Netflix comedy special
Dave Attell: Hot Cross Buns. ==Personal life==
