Consider this piece of code

    console.log(this.isCrazy); // wrong.
}
crazy.isCrazy = \'totally\';

As rfw said, this is the most straight forward way to go if the function has one single name:

var crazy = function() {
    console.log(crazy);
    console.log(crazy.isCrazy);
};

crazy.isCrazy = 'totally';
crazy();

In case it may have different names, or you wanted to pass it around, it must be wrapped in a closure:

var crazy = (function(){
    var that = function() {
        console.log(that);
        console.log(that.isCrazy);
    };
    return that;
})();

crazy.isCrazy = 'totally';
crazy();
