Fifteen minutes into the flight from Kansas City to Toronto, the captain announced, "Ladies and gentlemen, one of our engines has failed. There is nothing to worry about. Our flight will take an hour longer than scheduled, but we still have three engines left."
Thirty minutes later the captain announced, "One more engine has failed and the flight will take an additional two hours. But don't worry ... we can fly just fine on two engines."
An hour later the captain announced, "One more engine has failed and our arrival will be delayed another three hours. But don't worry ... we still have one engine left."
A young child passenger turned to his mother in the next seat and remarked, "If we lose one more engine, we'll be up here all day!"

Four high school boys afflicted with spring fever skipped morning classes. After lunch they reported to the teacher that they had a flat tire.

Much to their relief she smiled and said, "Well, you missed a test today so take seats apart from one another and take out a piece of paper."

Still smiling, she waited for them to sit down. Then she said, "First Question: Which tire was flat?"

A man came home from work after a horrible day at the office. His wife has complained to him over and over that he never notices her anymore, and he denied it. When he comes through the door his wife greets him and says,
"Hi, Honey. Notice anything different about me today?"
"Oh, I don't know. You got your hair done."
"Nope, try again."
"Oh, uh, you bought a new dress."
"Nope, keep trying."
"You got your nails done."
"Nope, try again."
"I give up, I'm too tired to play 20 questions."
"I'm wearing a gas mask!"

A biology graduate student went to Borneo to take some samples for his thesis work. He flew there, found a guide with a canoe to take him up the river to the remote site he where he would make his collections. About noon on the second day of travel up the river they began to hear drums. Being a city boy by nature, the biologist was disturbed by this. He asked the guide, "What are those drums?" The guide turned to him and said, "Drums OK, but VERY BAD when they stop."
Well the biologist settled down a little at this, and things went reasonably well for about two weeks. Then, just as they were packing up the camp to leave, the drums suddenly stopped! This hit the biologist like a ton of bricks (to coin a phrase), and he yelled at the guide,
"The Drums have stopped, what happens now?"
The guide crouched down, covered his head with his hands and said:
"Bass Solo"
