Get Away with Murder

Two prisoners are talking about their crimes:
George: "I robbed a bank, and they gave me 20 years"
Herman: "Hmm. I killed a man, and I'm here for 3 days"
George: "*WHAT*??? I rob a bank and get 20 years; you kill a man and get 3 days???"
Herman: "Yeah, it was a lawyer."

The Judge and the School Teacher

When asked for her occupation, a woman charged with a traffic violation said she was a school teacher. The judge rose from the bench. "Madam, I have waited years for a school teacher to appear before this court," he smiled with delight. "Now sit down at that table and write 'I will not pass through a red light' five hundred times!"

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.
