There is an old hillbilly couple a sittin' on their porch, just a rockin'. It's their anniversary, and they've been married 60 years. There're just a sittin' and a rockin'.

Suddenly, the old lady looks over at the old man and hits him so hard she knocks him clean out of his rocker and he falls on the porch. He pulls himself up and clambers back into the rocker and asks, "What the heck was THAT for?!"

"That's for 60 years of lousy sex!" she replies.

So they sit there for a time longer, not sayin' anything, just a rockin', and suddenly the old man looks over at his old wife, and gives her a shove so hard it knocks her right out of her rocker. She shakes herself off, and scrambles into her rocker again, and says, " What the heck was THAT for?"
