A man was standing in the center of his kitchen, perfectly still, holding a fly-swatter in an upraised-ready-to-strike position. His wife walks in - he doesn't move a muscle - and she stares at him for a second, then she says "What are you doing?" "Hunting flies" he says. "Really"... she says, then she sarcastically asks "Having any luck?" "Yup" says he... "Four males and 3 females". "How can you tell the differance?" "Easy" he says... "two of the males were on my beer can, the other two were on my steak sandwich... all the females were on the telephone."
