The 14th of February sounds good. That gives us time to acquire the necessary items. You know, like flour, sugar, butter, jars, butyric acid to pack the cupcakes in so when the jar is opened - it will be, since no cupcake deserves to be wasted - immediate gagging and puking by all who smell it will ensue. Butyric Acid is not really dangerous, except to delicate senses, like smell. It does no permanent damage. It is a natural component in butter, parmesian cheese, and vomit and is used as a farm additive to promote plant growth. It's cheap and is available at Amazon.
