The slide deck from a "Javascript For Beginners" training session I ran in our office earlier this year. Of course, some of the slides won't make sense out of context, but whatevs, right?
Also, be warned that I was pretty sleep-deprived when this all happened, and a side effect of that was that I swore a LOT during the presentation. Some of that leaked it's way into the slide deck. Maybe don't show this to your mom.
