When they say that this is possibly the most useful video you'll ever watch in terms of saving you time in your life, they're not kidding. The shirt removal video alone is worth the price of admission.
The 'bonus' video of the greatest proposal ever though, don't let your girlfriend, wife or fiance watch that lest they be very jealous and ask "why didn't you do something like that for me? Don't you love me as much as he does her?" (might be just me projecting though).
