Did you happen to see the post about the fat idiot who totally believed that an ice cream recipe she found on Pinterest had only 40 calories in whole serving? (It was a typo by the Pinterest user who submitted it, missing a digit or some such). Anyway, this recipe had a whole can of full fat coconut milk, 97 grams of sugar (if I recall) and some other stuff.  I mean....how can you just not know that there is no way on earth that a cup of this "ice cream" would exceed 40 calories by a wide margin?  How?!    Willful ignorance, indeed.
