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 a beer can and 2 were on the phone."
