The scientist who swallowed his hypothesis.

Here's the strange part.

Barry Marshall gave “testing your own idea” a dangerous literal meaning when he swallowed a culture of Helicobacter pylori in 1984. He developed gastritis, and the bacterium was later cultured from biopsies. The episode helped challenge established thinking about stomach disease, but this single experiment did not produce a demonstrated ulcer. It belongs in history, not on a list of things to try.
