My top-10 most popular episodes of The Tim Ferriss Show, as of September 1, 2017, are below.
But achtung! I didn’t rank episodes in descending order of total downloads. Due to rapid growth, there would be a misleading recency bias — in other words, a newer decent episode could be “more popular” than an older blockbuster episode that was 3x the average at the time. To correct for this, we used a better methodology, and I owe special thanks to my brother for the help.*

*Explanation from my statistician brother: “I first modeled the growth of the podcast over time. I used a linear regression model after a logarithmic transformation. (A logarithmic transform, which implies that the downloads have been growing exponentially, was the near optimal box-cox transformation.) I calculated the standard error at each point using the 95 percent prediction bands. For each podcast episode, I then calculated the residual (the difference between the observed downloads and the regression line) and then standardized this difference by the standard error. I then ranked episodes according to this metric, by how many standard deviations they exceeded the mean trend line.”
