    Looks like I was able to work through a solution. It involved a few factors going wrong with the original:

    1. Since the original writing of the code I saw, jQuery added another optional parameter named easing. This really messed with how I was delegating to the original show method in jQuery by calling _oldShow.apply(...).
    2. After I fixed that, I found that sometimes the show method calls a series of other methods that sometimes recursively call show again. I needed a way to not have my implementation intercept those recursive calls; I found that I could rely on if there was a selector property or not.

    A working implementation can be found here at this jsFiddle:

    This implementation is pretty dependent on jQuery not changing the method signature of the show method though. So you pretty much have to decide if you want to modify your 3rd party jQuery plugins instead of doing this. Either way, if you want to get latest of the 3rd party plugin or the latest jQuery, some new change could break your implementation. So this solution is not necessarily better or worse than modifying your third party plugins.
