I like the different acronym mistakes people always (and very authoritatively) make for utm. "It stands for Universal Task Module" "Nope, it stands for Universal Tracking Monitor!" ... inevitably the old guy jumps in, "Kids, let me tell you about back in the day when we used Urchin"

For a while the JS that Google handed off to you was "urchin.js"

For years, actually. I kind of chuckled when they finally changed it.

btw, they still have urchin.js file on GA servers
