Toby, the vegetable vender and Mary, the melon vender had places near each other at the fair each weekend. As was the custom in that town, near the end of the day the vendors would swap their remaining products among themselves. Throughout the summer Toby and Mary became friendly with each other and visited between customers. On the last day of the summer fair Toby took a basket of vegetables that he knew her family liked over to Mary's table. Mary also had put together a basket of melons for Toby that she knew his family liked.
Toby offered first, picking up a bunch of handpicked greens he held them out and said, "Lettuce, Mary?"
Mary responded by offering a large melon and saying, "Cantaloupe, Toby!"
