Yesterday's "it-certainly-can't-go-on-much-longer" snowstorm forced First Lady Nancy Reagan to cancel a trip to Carnegie Hall in New York to attend pianist Vladimir Feltsman's first public concert in this country. Mrs. Reagan had promised the Soviet e'migre' -- a "refusenik" for eight years before being granted an exit visa to Israel this summer -- that she would attend last night's debut.

"She's very disappointed," Press Secretary Elaine Crispen said of the first lady, "but between Mother Nature and doctor's orders, it's better she stayed at home." Feltsman invited Mrs. Reagan to the concert after performing at the White House Sept. 27. Ron Reagan was to stand in for his mother at Carnegie Hall, and the first lady has been invited to Feltsman's concert at the Kennedy Center Nov. 22.

Redskins quarterback Jay Schroeder obviously sent in his answer long before leading his team to a come-from-ahead defeat in Philadelphia last Sunday. The promoters of "Walt Disney's World on Ice," which opened last night at the Convention Center, sent out questionnaires to a number of Washington celebrities asking which was their favorite of the Seven Dwarfs and why. Among the responses they received was one from Schroeder, who checked Happy, and explained: "I don't let anything bother me and I always like to make people smile." Redskins owner Jack Kent Cooke wasn't smiling a lot Sunday when Schroeder completed only 16 of 46 passes. Maybe now we know too why Channel 9's theater/movie critic Davey Marlin-Jones wears that absurd hat. His favorite dwarf is Dopey, because "I had the same kind of ears that he had when I grew up." But leave it to comic Mark Russell to put the promotional stunt in perspective. Russell wrote: "Which one of the seven dwarfs do I most identify with? It's a tossup between Bashful and Bruce Babbitt" ...

Washington real-estate broker Pat Dixson had a tough day Saturday. Her phone was ringing constantly, not with calls from clients looking for new homes, but from people shocked to learn that she was auditioning for a Playboy magazine picture spread. A story in this newspaper ran with a photograph of Patricia Dixon -- a blond Fairfax attorney who is also a real estate agent -- posing with Playboy photographer David Chan. Washington's Pat Dixson, also blond, said she kept reassuring her callers, "I'm a nice Christian girl from North Carolina. I wouldn't do that" ...

Berke Breathed's "Bloom County" comic strip is in trouble again. For the second time in a week, the word "sucks" has appeared in the strip, and at least one newspaper chain has canceled it. Nineteen Sunday papers and one daily -- the Fort Smith Southwest Times Record -- of the Donrey Media Record have decided to drop the strip, but, according to William Dickinson, general manager of Breathed's syndicate, The Washington Post Group, the chain had actually made known its intention to drop "Bloom County" before the dispute over the word began last week. A spokesman for Breathed said that in using the phrase "Reagan sucks" in the strip, the Pulitzer Prize-winning cartoonist was simply referring to the common, slang usage that comes from the saying "sucks eggs." Breathed reportedly doesn't plan to use the word again any time soon. In Pueblo, Colo., a radio station reporter says he will fill the "Bloom County" gap in his local paper by reading the strip on the air every day ...
