Why do you need to invoke an anonymous function on the same line?

I was reading some posts about closures and saw this everywhere, but there is no clear explanation how it works - everytime I was just told to use it...:

    Anonymous functions are meant to be one-shot deal where you define a function on the fly so that it generates an output from you from an input that you are providing. Except that you did not provide the input. Instead, you wrote something on the second line ('SO'); - an independent statement that has nothing to do with the function. What did you expect? :)
