Fly Swatting

A woman walked into the kitchen to find her husband brandishing a fly swatter and said: “What are you doing?”

“He replied I am swatting flies”

“Did you get any?” His wife enquires

“yes 5 of them 3 males and 2 females.”

His wife sneers at him and says “You can’t possibly tell what sex they are!”

The husband replied, “Yes I can three were on that empty beer can and the other two on the phone!”
