P.C. is exactly right.
But I am thinking about packaging one for a friend in Edmonton. It's her bday later this month, and I KNOW she will like it, espcially if I include a candle and a bday hat! I know she will actually make the cake. (then she will ask me for the recipe). She usually has the maturity of a 12 year old (as do I at times)...so we were good friends all through high school and collectively responsible for a ton of immature practical jokes....when we were considerably older than 12. We nailed people with pie-in-the-face on a few birthdays, and sent a lot of anonymous love letters to unsuspecting boys...just to see what would happen.
