There were 11 people hanging onto a rope that came down from a plane. Ten were Antartians, and one was a university professor. They all decided that one person should get off because if they didn't then the rope would break and everyone would die.

No one could decide who should go, so finally the professor said, "I'll get off."

After a really touching speech from the professor saying how and why she would get off, all of the Antartians started clapping.
