Joe and Mark, two small-town merchants were visiting New York City for the first time to attend a conference. There was a large party thrown, with lots of food and refreshments. At the end of the party, they both went outside.
Joe crossed the street, while Mark wandered into a subway entrance. When Joe came back, he noticed Mark emerging from the subway stairs.
“Where did you go?” Joe asked enthusiastically.
“I don’t know,” gushed Mark, “but you should see the train set that guy has in his basement!”
