This man is very naughty - and hilarious. Comedian Dave Attell, one of Entertainment Weekly's "25 Funniest People in America," has appeared on HBO with his own "HBO: One Night Stand," "Comedy Central Presents, Dave Attell," "The Late Show with David Letterman," "Late Night with Conan O'Brien," "The Daily Show with Jon Stewart" and CBS' "Everybody Loves Raymond." Attell is perhaps best known as the writer and host of Comedy Central’s hit show, "Insomniac with Dave Attell." "Quite simply, it's foul-mouthed, sophomoric, tawdry, and incredibly fun, combining the elements of travelogue, documentary and boys' or girls' night out," wrote the Los Angeles Times. Dave was also the star and creator of Showtime's "Dave's Old Porn." Lastly, Dave had a memorable role in Amy Schumer's "Trainwreck." Dave Attell is one of the best stand-ups around.
