Some words coined by Robert Heinlein include "grok" from "Stranger in a Strange Land," "waldo" from "Waldo," and "TANSTAAFL" from "The Moon is a Harsh Mistress."

"TANSTAAFL" stands for "There Ain't No Such Thing As A Free Lunch." It is a popular phrase that reminds us that everything has a cost, and nothing comes without some form of payment or trade-off. It is often used in economics to emphasize the idea of scarcity and the need to make choices.

Can you get an iPad? Yes, easily; call any of a dozen vendors and give them your credit card number, and it'll be there in two days.

Can you get a FREE iPad on the internet? No. NOTHING is free. TANSTAAFL.

The slogan is God gave you freedom, so let the Libertaian Party let you use it!!!!
