Three guys- a Cyclone, a Hawkeye and a UNI Panther are out walking along
the beach together one day. They came 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 Panther says, "I am studying to be a farmer; my dad was a farmer
and my son will also farm.  I want the land in NE Iowa to forever be
fertile."

With a blink of the Genie's eye, "FOOM" the land in NE Iowa was made
forever fertile.

The Hawkeye was amazed, so he said, "I want a wall around Iowa City,
so that no one can come into our precious town."

Again, with a blink of the Genie's eye, "POOF" there was a huge wall
around Iowa City.

The Cyclone, being an engineer, says to the Genie, "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
nothing can get in or out. So, what do you want for your wish?"

The Cyclone says, "Fill it up with water."
