Whatever it is, the difference is becoming less and less every year.
"I really love the guy who's on that show" he said to critics at TCA. "He's everything that I'm thinking and feeling and who doesn't have to behave the way society wants everyone to behave. I'm getting closer to that guy every day."
Many viewers weren't expecting a sixth season of "Curb," which starts up Sept. 9. Season five ended with Larry going to heaven, a seemingly perfect way to say goodbye.
But soon after that, back in his production office with nothing to do, David felt miserable. So he started thinking ideas for another season. And, as he told critics in his condescending but hysterical way, the process of thinking up new ideas also made him miserable.
So either way -- working or not working -- he wasn't a happy man.
So who's smiling now? Probably HBO, which is currently restocking its series pipeline, yet needs popular long-running skeins to placate auds who want something new while clinging to the old favorites.
Pressed on whether the cult-comedy would come back for a seventh season (after a long hiatus before the upcoming sixth), David said that show has shot an ending that "could be the last-show ending - or it might be the last-show ending."
David has famously equivocated about a new season for the past couple years; he quipped that he did that because knowing there might not be another season was the only way he could get through the current one.
If series does return, David took a cue from a reporter about how to advance the arc: by emulating his real life (in which he has formally separated from his wife, enviro-activist and producer Laurie David) and getting divorced from onscreen wife Cheryl Hines. "Sorry," he said, turning to Hines.
"You're off the show," David deadpanned, as only he can.
