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.

"Yep, 3 males, 2 Females," he replied.

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

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