All food eaten while standing has no calories. Exactly why is not clear, but the current theory relates to gravity. The calories apparently bypass the stomach flowing directly down the legs and through the soles of the feet into the floor, like electricity. Walking seems to accelerate this process, so that a frozen custard or hot dog eaten at a fayre actually has a calorie deficit.
Anything produced, purchased or intended for minors is calorie-free when eaten by adults. This category covers a wide range, beginning with a spoonful of baby tapioca, consumed for demonstration purposes, up to and including *biscuits baked and sent to college.
If you have a drink in your right hand, anything eaten with the other hand has no calories. Several principles are at work here. First of all, you're probably standing up at a cocktail party (see "Food on Foot"). Then there's the electronic field: a wet glass in one hand forms a negative charge to reverse the polarity of the calories attracted to the other hand. I'm not exactly sure how it works, but it's reversible if you're left-handed.
All cakes are horrendously fattening. However, the calories can be eliminated simply by inscribing "Happy Birthday, Bob" or "Good Luck, Pauline" in coloured icing. Not only is it unnecessary to decline, it's impolite.
Movie related foods do not have additional calories because they are part of the entertainment package and not part of one's personal fuel. (Examples: Milk Duds, buttered popcorn, Junior Mints, Red Hots and Tootsie Rolls.)
Anything somebody made 'just for you' must be eaten regardless of the calories because to do otherwise would be uncaring and insensitive.
Remember, "stressed" spelled backwards is "desserts."
