Do you need more energy? Do you have trouble waking up in the morning? Do you drink two, four, or even eight hundred cups of coffee a day just to keep yourself going? What you need is a delicious, nutritious health food to give you yet another extra energy boost. What you need is Pei Tien Energy 99 Cake!
These tasty cakes come in a variety of flavors (including taro), and they give you a predictable amount of energy: 99, to be exact. Well, it’s not exact, really, since the units of energy aren’t specified. So it could be 99 joules, 99 ergs, 99 foot-pounds, 99 Btu, 99 hartrees, 99 electronvolts, or 99 Gordons. In fact, the failure to specify the units of energy for these cakes ranks up there with the Mars Climate Orbiter in terms of utter unit failure.
The Energy 99 cakes do taste quite a bit like egg yolks, and live up their claims of being delicious and (probably) nutritious. But by specifying their energy as dimensionless quantity of 99, they could result in an interplanetary disaster if they were ever used to fuel a mission to Mars. It’s a good thing we have rocket scientists to make sure something like that could never happen.
