Not the write stuff, ant prank, rewiring engineers

What was causing an Afghani man's headaches?

A pencil. It was not a case of writer's block but a physical pencil about 4 inches long. The man had finally sought help after suffering for years from headaches, constant colds and worsening vision in one eye. A scan showed that a pencil had somehow become lodged in the man's head from his sinus to his pharynx, injuring his right eye socket. The unnamed man said he didn't know how the pencil got there, but recalled that he once fell badly as a child. German doctors removed the pencil and say the man has recovered.

What prankster kept ringing a German woman's doorbell?

The police caught the culprits but they weren't exactly pulling practical jokes. Officers were called to the home of a 75-year-old German woman at about 3 a.m. because someone kept ringing her doorbell and was keeping her awake. Police found an ant nest next to the doorbell, which had grown so large it was pressing against the switching elements, keeping the bell ringing. Officers silenced it by removing the nest with a knife.

How is one university trying to rewire some of its students?

Northwestern University is teaching swing dancing. The idea is to get engineering students -- who are known for left-brain thinking -- to operate outside their comfort zone and use more of the right side of their brains. Students say the for-credit class, called Whole Body Thinking, is teaching them to think on their feet and work collaboratively with dance partners -- skills they say will help make them better engineers.
