A woman walked into the kitchen to find her husband stalking around with a fly swatter.
"What are you doing?" she asked.
"Hunting flies," he responded.
"Oh! Killing any?" she asked.
"Yep, 3 males and 2 females," he replied.
Intrigued, she asked, "How can you tell?"
He responded, "3 were on TV remote and 2 were on the phone."
