How to know if a fly is male or female
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, 2 females,’ he replied.
Intrigued, she asked.
‘How can you tell them apart?’
‘3 were on a beer can, 2 were on the phone’
