A primary school teacher in the Bronx decided to see how many of the city kids knew what sounds farm animals made. She asked the kids to put their hands up if they knew the correct sound.
“Who knows what sound a cow makes?” she asked.
Mary put her hand up and said “Moooo!”
“Very good” replied the teacher, “what sound do sheep make?”
“Baaaa” answered Johnny.
She continued this for a while.
Then she asked “What sound does a pig make?”
All the hands in the class went up. She was surprised at the response. She chose the shy little boy at the back of the class.
He stood up, took a deep breath, and screamed, “Up against the wall, motherfucker!”
