The Washington Post's Mensa Invitation once again asked readers to take any word from the dictionary, alter it by adding, subtracting or changing one letter, and supply a new definition. Here are this year's winners. Read them carefully. Each is an artificial word with only one letter altered from a real word.
1. Intaxication: Euphoria at getting a tax refund, which lasts until you realize it was your money to start with.
2. Reintarnation: Coming back to life as a hillbilly.
3. Bozone (n.): The substance surrounding stupid people, that stops bright ideas from penetrating. The Bozone layer, unfortunately, shows little sign of breaking down in the near future.
