I was upgrading jQuery, and had a lot of different versions on the site. One of them was this gem: https://gist.github.com/jcampbell1/8601940/raw/f409862786b8f577aed91236ee37005321f64c51/old+jquery https://gist.github.com/jcampbell1/8601940/raw/f409862786b8f... I think it is jQuery version 0.3. It was actually being used on a few minor pages, and still worked on modern browsers.
