"Here is what Avner does best: he reduces his audience to laughter and giggles and applause."
-The New York Times

"I laughed for two solid hours. The show only lasted an hour and a half. I wanted more. Avner the Eccentric is a brilliant comic."
-Joel Siegel, ABC TV

"A rare chance to experience the talents of a widely respected comic master...performed not only with great skill but with a spontaneity that makes them seem newly minted."
-San Francisco Chronicle
