Rancid Butter?

I thought I had made it quite clear and understandable to Baby Wingnut earlier in the week.  You have to have butter on your toast if you want the cinnamon and sugar to stick.  I very calmly and clearly explained this to him and he happily acquiesced.  Our agreement quickly fell apart this morning with Baby Wingnut loudly declaring there was to be no butter on his toast.  I asked his older brother to spread some on, on the sly, but Baby Wingnut is way too observant.  He fell in a heap on the kitchen floor and wailed, "No stinking butter on my toast!"
