Wills
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, three males, two females," he replied.
Intrigued, she asked: "How can you tell them apart?"
He replied:"Three were on a beer can, two were on the phone".
