The easiest way for anyone to remember or have many complex topics explained is via a story and especially one with comedy, due to the strong emotional/physical response it creates.
Also, this talk is not just another run of the mill explanation, but it is done from an unusual perspective (copyright math "expert"), which also helps to get the point across.
For those not already aware of the basic issues involved (which arguably is most people otherwise we would not be in the situation we are now), I am betting they, possibly including your "parents", will learn and remember far more from this talk than any facts/figures/reports you could possibly direct them to.
