Sarah was reading a newspaper while her husband was engrossed in a game on TV.

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

"Hmmm," her husband said, not bothering to look away.

Sarah said teasingly, "Would you swap me for season tickets?"

"Absolutely not," he said, "season's more than half over."
