Nun on the scale
A nun was going to Chicago. She went to the airport and sat down, waiting for her flight. She looked over in the corner and saw one of those weight machines that tells your fortune. So, she thought to herself, "I'll give it a try just to see what it tells me."
She went over to the machine and put her nickel in and out came a card that said, "You're a nun. You weigh 128 lbs., and you are going to Chicago, Illinois."
She sat back down and thought about it. She told herself it probably tells everyone the same thing, but decided to try it again. She put her nickel in, and out came a card that read, "You're a nun. You weigh 128 lbs. You're going to Chicago, Illinois, and you are going to play a fiddle."
The nun said to herself, "I know that's wrong. I have never played a musical instrument a day in my life." She sat back down. From out of nowhere, a cowboy came over and set his fiddle case down next to her. The nun picked up the fiddle and started playing beautiful music.
Startled, she look back at the machine and said, "This is incredible! I've got to try it again!
Back to the machine she went, put her nickel in, and another card came out. It said, "You're a nun, you weigh 128 lbs., you're going to Chicago, Illinois, and you're going to break wind."
Now, the nun knew the machine was wrong. "I've never broken wind in public in my whole life!" Just then, she tripped, fell off the scales and broke wind.
Stunned, she sat back down and looked at the machine. She said to herself, "This is truly unbelievable! I've got to try it one more time."
She went back to the machine, put her nickel in and collected the card. It said, "You're a nun, you weigh 128 lbs., you have fiddled and farted around and missed your flight to Chicago!!!"
