The Three Little Pigs
A teacher was reading the story of the Three Little Pigs to her class. She came to the part of the story where the first pig was trying to gather the building materials for his home.
She read, "And so the pig went up to the man with the wheelbarrow full of straw and said: 'Pardon me sir, but may I have some of that straw to build my house?"
The teacher paused then asked the class: "And what do you think the man said?"
One little boy raised his hand and said very matter-of-factly "I think the man would have said: "Well, fuck me! A talking pig!"
The teacher was unable to teach for the next 10 minutes.
