Carnal knowledge of a watermelon

I knew a guy once who grew up on a farm in Mississippi who fucked watermelons. Apparently on a hot summer day you can just cut a hole in a watermelon and stick your dick in and the interior feels like a warm, soft, exceptionally juicy pussy. He says if done right it is impossible to keep from cumming for more than a minute or two.
One day my friend and two companions were in a watermelon patch by the side of a country road having a good time. A car came by, driven by an older lady, and she was so shocked by the spectacle of three young guys humping watermelons that she drove her car off the road and into a power line pole. Of course, being good country boys, they didn’t run off but stayed to help her.
The investigating deputy sheriff later admonished them by saying, “Now, boys, it is perfectly natural to fuck watermelons, but from now on do it out of sight of the road!” This seems to suggest that, at least by Mississippi standards, fucking watermelons is a normal practice. What do you think?

I swear to God, this is a true story; no one could make something like this up. Has anyone else heard anything like this?
