Remember 360 Vodka's twist on the formulaic "X-ing the Y, One Z at a Time"?
(Sorry I couldn't find a bigger photo; the slogan reads "Saving the planet, one glass at a time.")
Here's a new variation I spotted the other day:
The snowclone "Changing the [world/earth/planet], one X at a time" appears to be more common than "Saving the [world/earth/planet], one X at a time" (584,000 Google hits for the first, with the "world" variant; 181,000 for the second). Snowclone queen Erin O'Connor includes "Saving the world, one X at a time" in her snowclones queue--a long list of snowclones awaiting analysis.
