The farmer's dilemma
A farmer has a dog, a sack of grain and a live chicken, all of which he must take across a river. The boat will only carry him and one of the things at a time or it will sink. Without the farmer, the dog would kill the chicken, and the chicken would eat the grain. How does he get all three across safely to continue his journey?
Answer: He takes the chicken and comes back; then he takes the grain and comes back with the chicken; then he takes the dog and comes back; then he takes the chicken.
