I will bake a cake/cupcake and dye it pink, everyone expects it to be the strawberry box mix but I will instead add a flavor to it like root beer, blueberry etc.
I went as far one year to make cupcakes for my job that it was my last day at. Everyone kept walking by and eyeing my cupcakes and I said "I'm leaving at 2, you can have them then!"
They were a triple chocolate with chocolate fudge filling with chocolate frosting... but had some garlic and onion powder added to it.
The chocolate smell was so overwhelming that you couldn't smell oh so subtle hint of the garlic or onion but you sure could taste it.
There was a reason why I made them wait... I heard them screaming for me down the hall as I walked out the door at 2:01. I laughed and let out a loud "GOTCHA!" as the door closed.
