Tony and his wife, Lynne went for a stroll in their local park one evening. They sat down on a bench to rest and almost immediately could overhear voices coming from a secluded spot behind them.
Suddenly Lynne realized that a young man was about to propose. Not wanting to eavesdrop at such an intimate moment, she nudged Tony and whispered, "Whistle and let that young couple know that someone can hear them."
Tony objected. "Whistle? Why should I whistle? Nobody whistled to warn me!!!"
