The teacher was explaining to her pupils the importance of responsibility and was looking to assign a team to do an important job for the class. She told them: "In this job we need someone who is responsible."
Little Johnny jumped up and shouted: "I'm the one you want teach'. On my last job, every time anything went wrong, they said I was responsible."
The teacher was trying to teach the class the proper words to use when describing bodily functions. She admonished the class to use the term urinate. To reinforce the lesson she asked the class to use their knew word in a sentence.
When she called on Little Johhny he said: "Teacher... urinate. But if you had bigger tits you'd be a ten!"
