Season 3 Episode 23 "White Gold" Hawkeye and Trapper run into Flagg in the mess tent. As Trapper warns Flagg about the dangers of the breakfast offerings, Hawkeye slips some pills into his coffee. Later, we see Flagg on an operating table, with Hawkeye and a nurse standing over him in surgical whites while Trapper does the anesthesia – the pills gave Flagg symptoms of appendicitis, and they remove his appendix to keep him from making off with their penicillin.

Season 7 Episode 23 "Preventive Medicine" After a couple of drinks mixed by Hawkeye with some pills , Lacy doubles over in pain, and while B.J. quickly diagnoses it as gastritis, Hawkeye believes it to be appendicitis, requiring surgery. Hearing this, Lacy protests, saying he'll lose his command if he's off the line for too long, which only empowers Hawkeye to order Lacy to be prepped for surgery.

Weary, Hawkeye later returns to the Swamp and quietly admits that he tossed Lacy's "pink and perfect" appendix into the scrap bucket. But then B.J. informs a disbelieving Hawkeye that more wounded are on the way, just a few seconds before the P.A. announces it. B.J. adds: "You treated a symptom- the disease goes merrily on." He helps a tired and frustrated Hawkeye back to his feet, and the two return to the OR.
