I saw Dave Attell at the Irvine Improv a number of years back, and he was drunk off his ass. He was so drunk, he literally had to hold himself up against the brick wall with one hand while the microphone lazily flopped in his other. For the majority of his set, he barely looked at the audience as he often lightly stumbled from one side of the small stage to the other. And you know what? He killed it. He absolutely fucking killed during his set.
This just comes to prove that a drunk Dave Attell is still better than 90% of the working-class comedians that are out there today, making shitty jokes about cliche' subjects like their marriage and flying.
Dave Attell has always been funny, and his delivery is unique in the ways he can segue from one subject to the next. What makes his segues funny is that they aren't flawless, and he just easily changes from a normal subject like "crappy music" straight into somehow relating it too venereal disease in a single moment.
I was a huge fan of his show "Insomniac" when it used to air on Comedy Central. Now you can see him on "Comedy Underground" on Sunday nights.
Here's the first part from his album, "Skanks for the Memories." Listen to the whole album if you get a chance. Dirty Attell at his best.
