My suspicions were confirmed Friday night at Borgata: I definitely don't have the Robin Williams gene.

That's the cellular mechanism that makes people think the veteran comic-actor is not only a singularly hilarious human being, but a bonafide genius whose lightning-like mind is almost supernatural.

There obviously were plenty of those gene-carriers at the Big B's Events Center Friday. They were the ones whooping and guffawing at most of what Williams had to say. And he had plenty to say. About everything from Atlantic City and GPS units to Sarah Palin and former Phillies star Lenny Dykstra.

It's not that Williams didn't prove to be extremely bright and clever, not to mention knowledgeable about a dizzying array of subjects. And there were plenty of punchlines that were amusing. Speaking of O.J. Simpson's book, "If I Did It," he suggested "Even the devil's saying, 'What a f-----g moron!'" He identified earthquake-prone San Francisco as "God's Etch-A-Sketch." And he described this difference between current Veep Dick Cheney and his would-be successor Palin: "If she shoots you in the face, you stay...down!"

Decent lines. But hardly the stuff of genius. At least for us gene-less types.

SIMON-IZED: They're probably still scratching their heads at the Big B over Carly Simon's set last Saturday night. According to a source who witnessed the whole sorry affair, Simon's performance was so awful--and the crowd let her know it-- she pretty much turned the gig over to her son, singer-songwriter Ben Taylor after five songs.

How hostile was the crowd? "The Borgata could have made a lot of money if they sold pitchforks at the box office," said our source.
