   Jokes You Can Tell in Class

   A teacher said to her student, "William, if both of your 
   parents were born in 1976, how old are they now?"

   After a few moments, William answered, "It depends."

   "It depends on what?" she asked.

   "It depends on whether you ask my father or my mother."
  1. Calculating the ages of William's parents also depends on _________________________________________.

  2. List the prime factors for 1976.

  3. The Wikipedia says that during January of 1976, the "Cray-1 -- the first commercially developed supercomputer -- was released by Seymour Cray's Cray Research." The Cray-1 weighed 5.5 short tons. The African elephant is the world's largest land animal and on average it weighs 15,400 pounds.

    No or Yes: The Cray-1 weighed more that the average weight of an African elephant.
    [1 short ton = 2000 pound]
