Ok, so I get the Family Fun Magazine, which I would totally recommand to anyone who does not presently own it. Anyway, every year they have ideas to have fun on April Fools Day. This year I finally did their ideas:
I turned their cereal milk blue! Jason told them that there was a new cow that made milk that turned blue when you poured it on your cereal. The girls bought it no problem. Our oldest looked at us like we had gone crazy. It took him a while even after we told him it was for April Fools Day to partake of his breakfast. 8-)
