The three little pigs

Once upon a time there was a mother pig who had three little pigs. The pigs were too old to live with the mother, so she made them move out and build their own houses. She also reminded them to look out for the big bad wolf.
The first little pig, who was a computer science major, decided to build a house out of straw, thinking it would be sturdy enough while still being nice and cool inside.
The second little pig, who was an architectural design major, decided to build his out of of wood, thinking that wood was what his mother pig used to build a house and what everyone else used.
The third little pig majored in engineering. He decided to build his house out of steel beams.
One day, a big bad wolf came around to the first little pig's house. He was very hungry, so he took a big bite out of the straw house and tore it down with his teeth. The little piggy was forced to flee to his second brother's house.
When the wolf arrived at the second little pig's house, he brought a bulldozer with him and started ripping through the house. The pigs were absolutely terrified, and they ran all the way to their big brother's house.
Before going to the third pig's house, the wolf knew that he needed something big.
The wolf went to the house of the third pig, and crashed two jets into the house. The third little pig laughed at the wolf, and calmly said to him, "Silly wolf, jet fuel can't melt steel beams!"
