Flies

  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.

"Yes, 3 males and 2 females" he replied.

Intrigued, she asked, "How can you tell?"

He responded, "3 were on a beer can, 2 were on the phone."
