How to Tell the Sex of a Fly
This is the cleanest E-mail joke
I've come across in a long while!
A woman walked into the kitchen to find her
husband stalking around with a fly swatter
"What are you doing?"
"Oh. Killing any?"
"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."
