Three guys, a Oregonian , a Californian and a Washingtonian are out
walking together one day. They come across a lantern and a Genie pops out
of it. "I will give you each one wish, that's three wishes total," says
the Genie. 

The Oregonian 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 Oregon." With a blink
of the Genie's eye, 'FOOM' the land in Oregon was forever made fertile
for farming.

The Californian was amazed, so he said, "I want a wall around California,
so that no foreigners can come into our precious state." Again, with a
blink of the Genie's eye, 'POOF' there was a huge wall around California.

The Washingtonian asks, "I'm very curious. Please tell me more about
this wall."

The Genie explains, "Well, it's about 150 feet high, 50 feet
thick and completely surrounds the state. Nothing can get in or out."

And the man from Washington says "Fill it up with water'.
