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?"
"3 were on a beer can, 2 were on the phone" he responded
