Lack of plumbing
I recently had a visitor from the state of Texas. For three days all I heard from him was, "In Texas we have the best this, the largest that, the fastest that," etc. It eventually became very annoying.
I am from Niagara Falls and I thought I could outdo him by showing him the Magnificent Niagara, knowing there was nothing in Texas that could compare to this Wonder of Water & Power.
While standing at the brink watching millions of gallons of water rushing over, I noticed the look of awe in his eyes. It was then I asked him, "Do you have anything like this in Texas?"
He waited a moment before he answered, "No, but we have a plumber that could fix it."
