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.
