Private Danny Baker appears in the Season 2 episode of M*A*S*H, titled "Operation Noselift". The part of Private Baker is played in the episode by Todd Susman.
Note that Susman also provided the uncredited voice of the M*A*S*H P.A. Announcer in numerous episodes -- including this one. As Baker is established as a long-serving member of the 4077th (who just happens not to have been seen in an episode before), it is possible that Baker is one of the two otherwise unknown announcers we regularly hear over the P.A.
About Private Baker's nose[]
As CO Henry dictates a letter to General Mitchell defending his appearance as King Neptune at a 4077th Mardi Gras celebration, the MP's deliver Baker, a Private with a rather large nose who is notorious for going A.W.O.L. Henry reads Baker the riot act, adding “stern measures” are needed, but admits he's not good at dispensing discipline. He's at a loss at what to do until Radar slips him a note suggesting the Colonel send Baker to Father Mulcahy for counseling. Baker tells Mulcahy his big nose is “ruining” his life.
The Father thinks the doctors may be of assistance, so he accompanies Baker to the Swamp to see Hawkeye and Trapper. The captains try to comfort Baker and admit it would be against regulations to do cosmetic surgery like a nose job. Baker pleads for their help and they finally relent, so Hawkeye and Trapper take the request to Henry. Henry agrees, but only unofficially, even going as far to have Radar forge the daily report making him absent (in one of those scenes only McLean Stevenson can pull off.)
Hawkeye enlists an old friend, Major Stanley "Stosh" Robbins (Stuart Margolin) is a Hollywood plastic surgeon in his civilian practice who is currently stationed at Tokyo General working with burn victims, whom he calls on the phone.
When "Stosh" arrives at the camp under the guise of meeting a fine "mystery woman" to get intimate with, or a real "barracuda" as friend Hawkeye describes her, is hell bent on meeting this “barracuda”, to the point of giving himself a headache, but Hawkeye tells him the nose operation has to come first! Baker is shown a book of nose profiles; he chooses the same one Robbins performed on his wife, and under the guise of a pass to Tokyo, leaves the camp, but under the suspicious eyes of Majors Burns and Houlihan.
As Hawkeye preps the O.R., Baker sneaks through the hillsides back into camp while Radar pretends to injure his nose in a baseball accident. All is ready except for Robbins who, thinking Margaret must be the “barracuda”, follows her into the supply tent. She is barely able to fight off his advances when Hawkeye arrives, looking for his friend. Trapper stays behind to console Margaret, while Hawkeye is able to whisk Robbins to perform surgery on Baker, which is a success!
