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.
"Are you killing any" she asked?
"Yep, 3 males and 2 Females," he replied.
Intrigued, she asked, "How can you tell them apart?"
He responded,
"3 were on a beer can and 2 were on the phone."
