Discrepancies in console.log() with Prototypes: Part 1 video

Hey all,

So, I'm working on the JavaScript Foundations > Prototypes videos, and as I'm going through them I'm following along. At the end of the lesson, though, my code doesn't seem to work, while Jim's does. Here's what I've got:

var personPrototype = {
    name: 'Anonymous',
    greet: function (name, mood) {
        name = name || "You";
        mood = mood || "good";

        console.log("Hello, " + name +
                    " I am " + this.name +
                    " and I am in a " + mood + " mood!");
    },

    species: 'Homo Sapiens'
};

function Person(name) {
    this.name = name;
}

Person.prototype = personPrototype;

tom = new Person("Tom");

According to the video, I should be able to input tom.greet and have "Hello You I am Tom and I am in a good mood!" log to the console, but instead I get:

function (name, mood) {
        name = name || "You";
        mood = mood || "good";

        console.log("Hello, " + name +
                    " I am " + this.name +
                    " and I am in a " + mood + " mood!");

which seems really strange. I've looked for stray and missing semicolons and whatnot; I imagine I'm just missing one, but I'm pretty stumped.

Thanks!

Looks like you just need to add parenthesis to the method call:

tom.greet();

Hah! I knew it had to be something like that. Thanks a million, Geoff!
