The Uselessness of Grade 10 Math

The crew of the Heart of Gold was out playing ball and a marvellous time was being had by all except for Marvin, of course. He was sulking off on the edge of the field, because he hadn't been built with a ball-playing function. He was complaining about this to everyone, but nobody was listening. Zaphod wasn't actually playing; he was instead sitting on the side of the field in a Comfo 5000 sipping something that was burning gradually through the bottom of the glass.

Ford threw the ball, which was large, red, and highly buoyant. In short, a beachball.

"Quick Arthur!" he shouted, "Draw a parabola to calculate the trajectory of the ball before it lands!"

"How…? I…?" said Arthur.

"Too late, it's landed," said Ford dejectedly.

"I calculated it," said Marvin, "But nobody thought to ask me."

"Yes, Marvin," said everyone wearily.

THE END

There was once this question in themath book that said something like: Calculate how many bananas you can fit into a locker.

I thought that was pretty funny.
