Pacific Repertory Theater’s production of Meshuggah-Nuns! The Ecumenical Nunsense is an evening of fun, without the guilt. Don Goggin’s fifth sequel to his popular Nunsense series is filled with slapstick and wisecracks poking fun at religions and our misconceptions of them, accompanied by high-kicking and rollicking (if not graceful) dance numbers and a beautifully sung mix of silly, poignant and soulful songs.

This time the four Little Sisters of Hoboken happen to be on a “Faith of all Nations” cruise ship when they are called upon to fill in for the ship’s regular entertainers, who were scheduled to perform Fiddler on the Roof, but who have fallen seasick. Only the production’s main star is able to join ecumenical forces with the irrepressible sisters for an uproarious, impromptu “Jewical” revue.

Parodies of Fiddler are found in “Contrition” (the sisters’ version of Fiddler ’s opening song, “Tradition”), “Three Shayna Maidels”, and “If I were a Catholic” a hilarious dance performed to klezmer music by the habit-wearing nuns with milk bottles balanced atop classic black, wide-brimmed hassidic hats, or streimels .

Another highlight is a big production number called “Das Boat,” one part “Gilligan’s Island”, one part “Love Boat” and a big splash of Poseidon Adventure, in which the plump Reverend Mother plays Shelley Winters’ character from the latter movie and swims to get help for a ship sunk by a tidal wave, all the while battling sharks and giant squid.

The entire cast is solid, energetic, and very talented, with first-rate singing voices that leave no gag untried. Gary Bolen, as Howard Liszt, the sole cast member left over from the original Fiddler production, is very good in “Matzo Man” (think “Macho Man”), and carries his own as the ship’s lone Jewish actor.

Amy Washburn, the Irish, “spirit”-loving Reverend Mother with the Sophie Tucker alter ego, has great delivery and presence. Shirley Smallwood portrays the no-nonsense Sister Hubert with soul to spare who really rocks in the final number, Lindsay Faye portrays the delightful, sweet and funny Sister Amnesia who is a couple of beads short of a rosary, and Mary Ann Schaupp-Rousseau shows her Brooklyn chutzpah as Sister Robert Anne, and her great vocal range in “I’ll Find a Song to Sing.” The live on-stage band is also a star, with additional kudos to musical director Stephen Tosh for never missing a beat in the musical pacing.

Director Jack Stauffer makes this show flow in a way that seems effortless, while technical director John Rousseau masterfully managed the myriad demands of lighting, props and set.

If you are hungry for laughter, and lines like “Cheeses of Nazareth, God is grated, God is Gouda” don’t offend your taste buds, then you are in for a treat.

Meshuggah-Nuns continues at the Golden Bough Playhouse in Carmel through July 3. 622-0100.
