So..the wife hears some noise while sleeping and goes downstairs to find the husband in his shorts in the kitchen holding a fly swatter.
She says, "What're you doing?" He says "Killing flies, I got 3 males and 2 females so far." She says "How in the world do you know the sex of the flies?".
He says, "Well, 3 were on beer cans and two were on the phone.":lol:
