Donna Marie Parker was a character who appeared in the Season 8 episode of the CBS-TV series M*A*S*H "Mr. and Mrs. Who?". The part of Donna is played in the episode by Claudette Nevins.
When Donna, a Red Cross nurse, arrives at the camp, Charles, who met her during a weekend of R&R in Tokyo, can't remember her or any part of the weekend, even a mock "marriage" ceremony that the two had a bartender perform for them, as he was blitzed, stone drunk at the time from too much boilermakers! They both collapse into laughter - one out of disbelief, the other - Charles - in relief! They spend the next few hours catching up on what happened, and Winchester admits that he likes this woman Donna quite a bit - even planting a gentle kiss on her.
The 4077th in celebration over the recovery of a soldier who was suffering from hemorrhagic fever from a solution which Hawkeye and B.J. had concocted, Hawkeye and B.J. also perform "un-nuptials" to officially dissolve the ersatz marriage of "Mr. and Mrs. Winchester". Margaret is the flower girl, and B.J. - whom Hawkeye refers to as "The Rev. J.B. Honeydue" - performs the ceremony, reading from a comic book.
