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.
