About Dr. "Bud"[]
Klinger accidentally breaks Potter's eyeglasses, requiring a visit from traveling optometrist Dr. Bud Herzog. Herzog's services is also needed by a young Korean farm boy named Park Sung (Rummel Mor), who as a kind gesture in repayment for the doctors looking after his grandmother, offered the 4077th fresh vegetables, of which was noticed in the improved quality of the food in the mess tent.
Park Sung, who's a whiz at farming (with help from a manual given to him by a G.I. friend), desperately needs new glasses, is helped by Hawkeye, who wonders if Herzog can make Park Sung new glasses as long as he'll be at the camp.
When Bud arrives, he arranges for new pairs of glasses for both Potter and Park Sung. He's a bit flattered, but perplexed when Margaret bluntly flirts with him, but it turns out its all a ruse: Margaret also has been having some trouble with her eyes, and she's sensitive about it, so she pretends she's there on romantic grounds.
Herzog comforts her that she's suffering from a mild allergy, nothing serious. Margaret is still concerned that her eyes aren't getting any better, that she's noticeably aging, but Herzog comforts her, and they fast become friendly. They decide to twist the knife on Hawkeye and B.J., and spend an evening at the O Club together, only to leave early. When Margaret picks up a basket of pretzels, Hawkeye asks why she's taking them. "Because", she says, lustfully, "I don't smoke"!
