Web Interest - What we should have been taught in high school - comic

Once again, this week's web interest is something I saw posted on a friend's Facebook.
It is a series of comics from  The Oatmeal, titled "What we should have been taught in our senior year of high school"
As a Canadian, I particularly enjoyed the 'Science' one (below), because we are taught in both systems since the U.S.A. is our neighbour.
The whole series (Science, Home Economics, P.E., Math, Economics, English, & Sex Ed)  is here: http://theoatmeal.com/comics/senior_year
