Dangerous Mix

This was a story told to us by our chemistry master at school. A female student wished to make some potassium hydroxide solution (aqueous) and decided to throw a large lump of potassium into a bucket of water. Her professor observed what she was about to do, out of the corner of his eye and hurried towards her, and after confirming this was what she was intending to do, asked her first to stir the water in the bucket for five minutes before adding the potassium. She was puzzled and ran after him to ask the purpose of this action. 'It will give me time to get away' said the professor.

Juggler Test

A juggler, driving to his next performance, was stopped by the police.
"What are those knives doing in your car?" asked the officer.
"I juggle them in my act."
"Oh yeah?" says the cop. "Let's see you do it."
So the juggler starts tossing and juggling the knives. A guy driving by sees this and says, "Wow, am I glad I quit drinking. Look at the test they're making you do now!"

Med Student

While making his rounds, a doctor points out an x-ray to a group of medical students. “As you can see,” he says, “the patient limps because his left fibula and tibia are radically arched.” The doctor turns to one of the students and asks, “What would you do in a case like this?”
“Well,” ponders the student, “I suppose I’d limp, too.”
