This code was forked from a different repository. As it is a relatively light Chrome extension, it was used to illustrate both basic GitHub concepts (forking, cloning) and some of the quirks of Javascript (mostly variable scoping) in the first recitation of my 6.170 Software Studio class. What follows is the original README:
Chrome extension that replaces occurrences of 'the cloud' with 'my butt'
Note that there are forks of this extension that simply replace 'cloud' with 'butt'. In my personal opinion, that approach is too broad and it's less funny as a result, but it is clearly a very polarizing issue in the cloud-to-butt user community. Forks are free to do whatever they like. But officially, this extension replaces only the phrase described above. Thank you for your concern.
