Fly Swatter ...

 

My friend Bruce was stalking around the house with a fly swatter when his wife came in.

 

"What are you doing?" she asked.

 

"Hunting Flies" Bruce responded.

 

"Oh, killing any?" she asked.

 

"Yep, 3 males, 2 Females," he replied.

 

Intrigued, she asked. "How can you tell?"

 

He responded,

 

3 were on the TV remote,

2 were on the phone.
