A woman walked into the kitchen of their house to find her husband standing there in the kitchen holding a fly swatter.
He was standing motionless, perfectly still, the fly swatter held up as if ready to strike.
“What on earth are you doing?” his wife asked him.
“I’m hunting flies” her husband responded proudly.
“Oh right! Have you killed any yet?” his wife asked.
“Yep, I sure have Doris” her husband replied with a grin, “I swatted three males and two females”.
Intrigued by his answer, she asked her husband “Flies all loothe same, how can you tell which is which?”
“Ah easy”, her husband replied, “three were on a beer can, two were on the phone!”
