While revising for tomorrow’s exam, I try to cover as many possible questions with as little revision material as possible. My grandfather always told this story from his school-days about a guy who took this logic to the extreme. On the day before a biology test in which one has to pick a note with a random animal out of a hat and then do an impromptu presentation on this animal, all students were reading about as many animals as they could. Except for one guy, who only learned about worms, and was somehow not worried at all. When it was his turn during the test the next day, he picked ‘Elephant’ out of the hat, and began his presentation with the words

“The Elephant is a large grey mammal, whose trunk resembles a worm. Speaking of worms…..” and then just proceeded to talk about worms.
