My mom started going to Weight Watchers, and during the lectures there's always someone who raises a hand to ask a question that involves some sort of "cheating" on the diet plan.  You know, if the plan calls for eating all you want of a vegetable for dinner, someone will ask, "Can I eat unlimited popcorn?"  They're willing to follow the strict rules, but their minds are racing to find loopholes that will allow them "legally" to gorge thousands of calories.  It's crazy, but I know all-too-well that when you feel like you're starving your brain will come up with all sorts of notions.  Inspired by my mom's Weight Watchers stories, I made up a joke:

A housewife went to Buddhist Weight Watchers.  The lecturer said, "The Buddhist way to lose weight is to follow the famous saying: 'Chop wood and carry water.'"  The housewife raised her hand and asked, "What about cutting coupons and retaining water?"
