Only episode that Colonel Blake's door to his tent opens by pushing to enter, so the cow could enter the tent for this episode. All the other episodes, the door is pulled to enter the tent.
Loretta Swit does not appear in this episode. Coincidentally, she also did not appear in "Deal Me Out" (1973), the only other episode guest starring Pat Morita.
While Colonel Henry Blake, Father Mulcahy, and Captain Sam Pak are sitting outside the mess tent eating spicy Korean food, it's interesting to note that Henry and Mulcahy, both Americans, eat using chopsticks, while Sam, a Korean, eats with a fork.
Second and final appearance of Pat Morita as ROK Captain Sam Pak. He previously appeared in the season 2 episode "Deal Me Out" (1973).
Clare Torao, who plays Choon Hi, later appeared (uncredited) in "Abyssinia, Henry," as one of the young ladies who serenade Henry at Rosie's Bar.
