I have this book called "The Teacher Teacher Joke Book" :D thanks to Linzhi, she lent this book to me until the whole family comes back from wherever they would be in these few years.. :P
Its a fun read, some of them aren't that funny because you'll need to have certain American background and understanding to get the joke. But here's one i'd like to share.

"For several weeks, a six-year old boy kept telling his teacher about the baby that was expected at his house.
One day, his mother put his hand on her tummy so that he could feel the movements of the unborn baby. He didn't say a word and even stopped talking to his teacher about it.
Several days later, the teacher asked him about the expected event. He began to cry and said, "I think Mommy ate it."

hehehe.... well i think its funny :P
and here's another one..

Teacher: Be sure that you go straight home."
Student: I can't; i live just around the corner.."

eheheh i hope every had a good day.. God Bless.
