Teacher: Who succeeded the first President of the USA? Class: The second one!

There's this black kid that goes to school and realizes teachers treat him differently than the white kids. So, he goes home, paints himself white and shows his dad. His dad beats the crud outta him. He shows his mother, "Hey Ma, Look! I'm white!" He gets beat by his mom too. Lastly, he shows his Grandmother, "Grandma, Look! I'm white! She beats him badly with her cane and sends him to his room. Later, his dad comes into his room and asks, "Son, did you learn anything out of this?" And the boy replies, "Duh! I've only been white for an hour and I already hate three niggers!"

Teacher: whoever answers my next question, can go home. One boy throws his bag out the window. Teacher: who just threw that?! Boy: Me! I’m going home now.

A teacher was giving a lesson on the circulation of the blood. Trying to make the matter clearer, he said: "Now, students, if I stood on my head the blood, as you know, would run into it, and I should turn red in the face." "Yes, sir," the boys said. "Then why is it that while I am standing upright in the ordinary position the blood doesn't run into my feet?" A little fellow shouted, "It's because yer feet ain't empty."

I hated my job as an origami teacher. Too much paperwork.
