Monthly ration/debit cards for your max sugar/sat.fat/animal protein allotment, plastered with Moo-chelle's ugly mug and wagging finger on one side, and her do-as-I-say-not-as-I-do My Plate logo on the other.

LOL! "First they came for my Big Gulp..."
Next they’ll make soft drink makers liable for damages for any customer who gets diabetes or a heart attack.
