"RTP Genie" joke
Three guys, a Tarheel, a Blue Devil and an NC State Wolfpack are out walking along the beach 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 Wolfpack says, "I am studying to be a farmer; my dad was a farmer and my son will also farm. I want the land in the Piedmont to forever be fertile."
With a blink of the Genie's eye, "FOOM" the land in the Piedmont was made forever fertile.
The Tarheel was amazed, so he said, "I want a wall around Chapel Hill, so that no one can come into our precious city."
Again, with a blink of the Genie's eye, "POOF" there was a huge wall around Chapel Hill.
The Blue Devil says, "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."
The Blue Devil says, "Fill it up with water."
