Old and New Jokes

A guy from Nebraska, a guy from Michigan, and a guy from Ohio are out walking along the beach together one day. They come across a bottle and a Genie pops out of it.
I will give you each one wish, thats three wishes total, says the Genie.
The guy from Nebraska says, I am a farmer, my dad was a farmer, and my son will also farm. I want the land to be forever fertile in Nebraska.
With a blink of the Genies eye, POOF the land in Nebraska was forever made fertile for farming.
The Michigan guy was amazed, so he said, I want a wall around Michigan, so that no one can come into our precious state. Again, with a blink of the Genies eye, POOF there was a huge wall around Michigan.
The Buckeye asks, Im curious. Please tell me more about this wall. The Genie explains, Well, its about 150 feet high, 50 feet thick and nothing can get in or out.
The Buckeye says, Fill it up with water.
