You're talking to a man who works as an encyclopedia salesman. His name is Grover Hayes, and he has a dog named Olivia. He used to have a wife named Olivia. He says the dog is an evil little thing, just like his former wife. The dog barks and growls at him as he talks to you, but he tells it to shut up. Grover Hayes isn't here on business, but he still insists encyclopedias are amazing things, with practical value. He's read all the encyclopedias he sells, and learned a great deal from them. Try volume 6, for example. It opens to page 3147. The heading is "magical formulas." Read it... you may learn something useful. Learn more about your ad choices. Visit megaphone.fm/adchoices
