An elderly woman came home to find her retired husband in the living room, waving a rolled up newspaper wildly around his head.
Wife: “What on earth are you doing dear?”
Husband: “I’m swatting flies. So far I got 3 males and 2 females”.
Wife: “How do you know which gender they were?”
Husband: “Easy. 3 were on the beer, and the other 2 were on the phone”.
