Kingsblood Royal by Sinclair Lewis

Mr. Blingham, and may he fry in his own cooking-oil, was assistant treasurer of the Flaver-Saver Company. He was driving from New York to Winnipeg, accompanied by Mrs. Blingham and their horrible daughter. As they were New Yorkers, only a business trip could have dragged them into this wilderness, and they found everything west of Pennsylvania contemptible. They laughed at Chicago for daring to have skyscrapers and at Madison for pretending to have a university, and they stopped the car and shrieked when they entered Minnesota and saw a billboard advertising "Ten Thousand Lakes."

Miss Blingham, whom they called "Sister," commented, "Unless you had a New York sense of humor, you would never be able to understand why that sign is so funny!"
