A woman walked into the kitchen to find her husband stalking around with a fly swatter.

She asked, 'What are you doing?'

He responded, 'Hunting Flies'

So she asked, 'Oh! Killing any?'

He replied. 'Yep, 3 males, 2 Females,'

Intrigued, she asked, 'How can you tell them apart?'



He responded: '3 were on a beer can, 2 were on the phone.'
