A joke
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."Yup. 3 males. 2 females" He responded.
Intrigued, she asked. "How can you tell?"
He responded, "3 were on the beer can, and 2 were on the phone."
