Whenever Bruce Springsteen does a concert, people beg him to play “Born in the USA.” For Billy Joel, it’s “Piano Man.” Paul McCartney always receives requests for “Yesterday.”

Lisa Kudrow?

She gets “Smelly Cat.”

At the Rock a Little Feed a Lot benefit concert for Feeding America, the nation’s largest domestic hunger-relief charity, at Club Nokia in Los Angeles Tuesday night, Kudrow, 46, took to the stage with longtime pal and onetime costar Courteney Cox Arquette to introduce singer Sheryl Crow – only to find herself with a guitar thrust upon her and the crowd chanting for her to play the magnum opus of Phoebe Buffay, the ditzy musician she played on Friends.

“Play ‘Smelly Cat!’ ” an audience member called out, after Kudrow and Cox Arquette were pressed into a question-and-answer session while Crow and her bandmates set up backstage.

Kudrow looked to her friend for help, but Cox Arquette gleefully threw her pal under the Benefit bus, calling out to the stagehands: “Get her a guitar, people!”

After being fitted with an acoustic guitar, the momentarily bewildered actress warily asked, “Is this a set up?” before summoning her inner Phoebe and serenading the audience with her ballad about an odiferous feline.

“Smelly cat, smelly cat, what are they feeding you?” she sang.

And the crowd leapt to its feet.
