Monkey patching

Recently, David Walsh tweeted that I had schooled him. I received several questions about what I had schooled him in, so I decided to blog about it. David was trying to change the behavior of a method of a widget on a page, but for all instances of that widget rather than just one instance. What follows is a lesson on monkey patching. I’m sure there are other tutorials out there about it, but this is more for my sanity (and to get David off my back about blogging) than anything else.
