McNally was taking his first plane ride, flying over the Rocky Mountains. The stewardess handed him a piece of chewing gum. “It’s to keep your ears from popping at high altitudes,” she explains. 

When the plane landed McNally rushed up to her. “Miss,” he said, “I m meetin me wife right away. How do I get the gum out of me ears?”
