The (maybe) last mention of the Redskins' fallen quarterback Joe Theismann and his lady love Cathy Lee Crosby (but no promises): There they are, photographed in the current People magazine, kissing passionately on his recovery bed at Arlington Hospital. And Cathy Lee talks of their upcoming marriage plans, joking that it won't be for at least three months because "honeymoons don't work with leg casts."

Not completely forgotten during all this Theismann publicity blitz is the ex-wife, Shari Theismann, who was at the game when Joe broke his leg and who stopped by the hospital in the early hours of the following morning to pick up their 14-year-old son Joey, who had also been there with his father. "I don't know if Miss Manners has a way for ex-wives to handle a broken leg," she said yesterday. She did send flowers in the children's names.

There were rumors that Shari had been banned from the hospital, but she said she didn't know anything about it "because I would never have tried to go up to see Joe." She thinks people are tired of the broken leg story and that it is the team that now needs the public's support. "I felt bad about him breaking his leg," she said and then quipped, "but for the first time in 16 1/2 years I know where he is and who he's with." The Donkey Rides On

Flash! The Democrats are not going to give up the donkey after all these years. It seems that New York magazine had jumped to conclusions -- as it often does -- when it learned that a top Hollywood designer was drawing up a new logo for party stationery. But yesterday, in the wake of the magazine's report, no less a party personage than Democratic National Committee Chairman Paul Kirk assured that "the donkey and the yellow dog are here to stay."

The donkey, like so many enduring American symbols, comes from the pen of legendary cartoonist Thomas Nast. It was in a cartoon that carried a caption that many today would say is in touch with 1980s Democrats: "The Democratic Party is like a mule -- without pride or hope of posterity." The yellow dog comes from Catholic Al Smith's unsuccessful bid for the presidency when so many Democrats were bolting the party because of his religious affiliation; one who stayed said, "I'd vote for a yellow dog if he ran on the Democratic ticket."

It should be pointed out that the Republicans are not expected to discard their venerable elephant, also invented by Nast. But the Democrats will have a decorator-designed letterhead by high-powered Hollywood creater Saul Bass, who came up with those symbols for AT&T and United Airlines. End Notes

A few people may have been surprised over the weekend to receive in the mail a slick "Sweepstakes" package to benefit the Kennedy Center, with prizes that included a full-length Black Diamond mink coat and a 13-day Mediterranean cruise. The sweepstakes didn't seem odd to Peg Allen, the director of membership for the Friends of the Kennedy Center, which is sponsoring it. She sees it as an extension of the Friends' direct-mail campaign and similar to fundraisers used by Arena Stage, the Metropolitan Opera and the Washington Performing Arts Society. She said this is a test year and the Friends hope to break even and make money next year . . .

All those people who were worried that movie mogul Steven Spielberg and the mother of his infant son, Amy Irving, weren't married need fret no longer. Santa Fe, N.M., Chief Judge Thomas A. Donnelly said he married the couple Wednesday in the New Mexico Court of Appeals . . .

On the hospital beat: Sen. Lawton Chiles underwent multiple coronary bypass surgery yesterday at Lakeland, Fla., Regional Medical Center. Recovery is expected to take a month but a spokesman said he was "doing great" . . . Margaret "Peggy" Goldwater, 76, wife of Sen. Barry Goldwater, had her leg amputated at midthigh Sunday at Good Samaritan Medical Center in Phoenix. The operation was required when two arterial-graft operations failed to cure circulation problems. She is listed in satisfactory condition . . . Jerry Lee Lewis yesterday left the Memphis hospital where one-third of his ulcerated stomach was removed last month. Said the piano-pounding singer, "I'll probably eat a bowl of chili, and an ice cold beer would be good."

Every U.S. senator was hand-delivered a Monopoly game yesterday and it wasn't a Christmas present. It was an attention-getting gimmick of the Independent Conrail Coalition for a Competitive Conrail and the Railway Labor Executives Association focusing on the proposed Norfolk Southern acquisition of Conrail. Apparently it would be like one person owning Short Line, Reading Railroad, Pennsylvania Railroad and B&O Railroad. That was always a good way to make a lot of money when an opposing player landed on your railroads. So that's how monopolies work . . .
