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, any luck killing any?" she asked.

"Yep.... 3 males, and 2 females so far," he replied.

Intrigued, she asked. "Now how the heck can you tell which were
which?"

He responded, "3 were on a tv remote, 2 were on the phone."
