A little trivia in case you don't know...
The opening credits for M*A*S*H usually went like this:
Alan Alda
Mike Farrell
Harry Morgan
Loretta Swit
David Ogden Stiers
Gary Burghoff
Jamie Farr
William Christopher
But for the first 5 episodes of the eighth season, the opening credits went as follows:
Alan Alda
Mike Farrell
Harry Morgan
Loretta Swit
David Ogden Stiers
Jamie Farr
William Christopher
and Gary Burghoff as "Radar"
This was because Gary Burghoff left at the end of the seventh season, but the networks didn't want to end that season with a good-bye Radar episode, so instead, he got called back to temporaily reprise his role as a guest the following season (mostly scenes of him calling back to the 4077th while on R&R whenever Klinger had trouble) until they did a two-part good-bye show for him. After that, his name was dropped from the credits for the rest of the season, and the rest of the series.
