A woman arrives in the kitchen and sees her husband with a fly swatter and says "What are you doing?" He replies: "I'm chasing the flies..." She asks "Did you kill them?" He says "As a matter of fact, yes, 3 males, 2 females" Intrigued, she asks him: "How do you make the difference between females and males?" He answers: "3 were on the beer can, 2 on the phone."
