There are three certainties in life: death, taxes, and your kids asking if they can have McDonald's for whichever meal of the day. I'm sure I'll deal with this a lot when my son gets older, but maybe I need to start saving those McDonald's wrappers so I can pull off the hack below.
Of course, I'll still take my son to the actual Mickey D's (he needs to get the toy somehow), but I might have to keep this hack handy from time to time!
