Much ado about ulcers and stomach acid; for a long time this acid/ulcer connection was considered fact. In 1987 a couple of Australian MDs published a paper indicating that the gram-negative bacterium Helicobacter pylori might be the true cause of ulcers. Other researchers soon confirmed this. About the time this episode came out, the NIH and CDC formally accepted H. pylori as the main cause of gastric ulcers.
The episode's title references the title of The Doors 1968 song "Hello, I Love You".
