Sarah was reading a newspaper, while her husband was engrossed in a magazine.

Suddenly, she burst out laughing. "Listen to this," she said. "There's a classified ad here where a guy is offering to swap his wife for a season ticket to the stadium."

"Hmmm," her husband said, not looking up from his magazine.

Teasing him, Sarah said, "Would you swap me for a season ticket?"

"Absolutely not," he said.

"How sweet," Sarah said. "Tell me why not."

"Season's more than half over," he said.
