Jay Leno may have blown his chance of bagging the first interview with embattled actor Mel Gibson once his war with Oksana Grigorieva ends, RadarOnline.com has learned.

Performing to a sell out crowd on Sunday evening at the Comedy and Magic Club in Hermosa Beach, California, the Tonight Show host silenced the audience with his opening comment about Gibson.

"That Mel Gibson, huh? What a mess. Mel Gibson actually had an uncle who died at a concentration camp... yeah, really," he told the crowd.

The audience remained silent, as Leno repeated: “Yep, died at a concentration camp.”

After a few more seconds pause, he sniped: “Yep, he fell out of the guard tower, drunk!”

Gibson has become accustomed to Leno’s couch in recent years, even taking to the Tonight Show studio in May of last year to announce Oksana’s pregnancy.
