The last use of Margaret's old nickname "Hot Lips". Radar says, "Wow-wow, Hot Lips!" when Margaret plants a kiss on him in Post-Op.
When Maj. Van Kirk arrives to claim the generator Klinger had hoped to procure for M*A*S*H 4077, Klinger mutters "You son of a dog!" ("Yah ibn el-Kelb!") in Arabic.
Radar saying goodbye to the rest of the cast provides a few nods to Abyssinia, Henry (1975):
- BJ gives him a kiss on both cheeks as Hawkeye did with Henry Blake.
- Colonel Potter hugs Radar as Henry did, but Radar's face is seen over Potter's right shoulder instead of the left.
- Father Mulcahy gives him the same "cross" gesture he gave Henry.
- Hot Lips kisses Radar much the way Henry kissed her.
The final appearance of Radar O'Reilly (Gary Burghoff) in the series. In addition to being on the show since Season 1, Burghoff is the only regular cast member to have starred in M*A*S*H (1970).
Gary Burghoff would play Radar again with a couple of guest appearances on the spin-off AfterMASH (1983), not to mention the failed pilot for his own spin-off W*A*L*T*E*R (1984).
