I am using jQuery UI and a few other JS libs which in total make for quite a chunk of JS (even minified and combined). My idea is to not include a script tag in the page but to stub out all functions that I defined as well as the $ sign for jQuery so that my inline JS on the page can still call them but will hit the stub. The stub will then load the .js file and actually call the function. The question now is:

*How can I redirect all function calls on the window object/global object to a custom function of mine?*

I am not used to dynamic languages so a little advice on how to do this in JS will be appreciated.
