A day job can lead to good ma terial. At least it did with “Exit Cuckoo,” Lisa Ramirez’s solo show about working as a nanny while pursuing a showbiz career in the Big Apple.

With acting jobs few and far between, the writer/performer winds up at the Kids First Domestic Agency, where she finds steady work even though she’s not Chinese, which seems to be preferred.

“Seems to be the latest trend — you know, the whole global economy thing,” her employer says.

On her first day at the playground, she surveys her fellow caregivers. “The benches are spread out like countries,” she says. “Latin America, Trinidad, Thailand, Poland, Ireland . . . it’s like the United Nations.”

In pungently amusing strokes, Ramirez depicts several nannies and their employers, including the Upper East Side mother who leaves such pithy notes as, “Off to get a brain scan, home before 6,” and the metrosexual couple who ask her to take their baby to Central Park for the Metropolitan Opera’s open-air “Faust.”

Ramirez is sympathetic to her fellow caretakers, who are often asked to work grueling shifts (“14-hour days — what is this, a plantation?”). She also seems to side with the Jewish grandmother who, aghast at the concept of mothers farming their kids out, declares, “Quantity time is what children need, not quality!”

Someone who doesn’t come off so well is her tough-talking female boss, who in one particularly distasteful monologue says parents would be better off with immigrants who, forced to leave their own children behind, will transfer their love to their charges.

While the piece suffers from occasional meandering and self-

indulgence — Ramirez spends a little too much time as, well, herself — it offers insight about a subject people thought they knew all about from “The Nanny Diaries.”
