A primary school teacher in the Bronx decided to see if city
kids knew what sounds farm animals made. She asked the
kids to raise their hands if they knew the correct sounds.

"Who knows what sound a cow makes?" she asked.

Mary put her hand up and said, "Mooooo!"

"Very good," replied the teacher. "What sound does a sheep
make?"

"Baaaa," answered Billy.

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 little Tyrone at the back of the class.

He stood up, took a deep breath, and screamed, "Up against
the wall, mutha-fucka!"
