I had only one superstition. I made sure to touch all the bases when I hit a home run.

The line plays on the idea of “superstition” in sports—rituals athletes use to manage uncertainty—by framing Ruth’s only “superstition” as something that is simply correct procedure. Touching each base after a home run is required; failing to do so can nullify the run if properly appealed. The joke underscores Ruth’s persona as both larger-than-life and practical: he dismisses mystical rituals while acknowledging the one habit that actually matters. It also hints at baseball’s rule-bound nature, where even the most spectacular feat must be completed by mundane fundamentals.
