Here's a Good One... Ol' farmer Bill done bought himself a new farm, and down yonder way in the back, there was this pond. Well, a few months later, after he got the place a runnin', he decided to go on down to that there pond with a pail and see what kind of grub he could rustle up. Hopin' to find some nice crawdads or some fish wallowing by the bank, he parted the cattails and looked out on the pond. And what do you suppose he saw? Well, out on the far end of the pond, to his surprise and theirs, too, was a couple of purty, skinny-dippin' girls! When they seen ol' John, they hollered out, "We ain't a comin' out til you leave!" "Oh, that's alright. You can all stay if you want." Farmer John replied,"I just come down to feed the alligators."

Ok, try this one...
Two elderly gentlemen are out by the pond, when suddenly a frog jumps out of the marsh. They are even more surprised when the frog starts to talk! "help me, kind sirs" it says, "for I have been turned into a frog by an evil witch, and the only thing that will turn me back into the beautiful princess I once was is a kiss. Why, if you help me, I could really show you a good time, if you know what I mean..." With that, one of the old men scoops up the frog, puts it in his pocket and starts to leave. "Hey," says the other, "Didn't you hear what she said? Ain't ya gonna kiss her?" "To heck with that," he said, "At my age, I'd much rather have a talking frog!"
