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”.
