Kids Think Quick

I get these jokes from an e-mail.
It must be frustrating to be an adult with a bunch of smart kids.
Being an aunt with two smart nephews, these are déjà-vu.
Thus I had made up my mind not to be a teacher no matter how noble the profession is. My sanity is at stake.
Enjoy.

TEACHER : Maria, go to the map and find North America.
MARIA : Here it is!
TEACHER : Correct. Now class, who discovered America?
CLASS : Maria!

TEACHER: John, why are you doing your math multiplication on the floor?
JOHN : You told me to do it without using tables!

TEACHER : Glenn, how do you spell "crocodile?"
GLENN : K-R-O-K-O-D-A-I-L.
TEACHER : No, that's wrong.
GLENN : Maybe it s wrong, but you asked me how I spell it!

TEACHER : Donald, what is the chemical formula for water?
DONALD : H I J K L M N O!
TEACHER : What are you talking about?
DONALD : Yesterday you said it's H to O!

TEACHER : Millie, give me a sentence starting with "I."
MILLIE : I is...
TEACHER : No, Millie..... Always say, "I am."
MILLIE : All right... "I am the ninth letter of the alphabet."

TEACHER: George Washington not only chopped down his father's cherry tree, but also admitted doing it. Now, Louie, do you know why his father didn't punish him?"
LOUIS : Because George still had the axe in his hand.

TEACHER : Now, Simon, tell me frankly, do you say prayers before eating?
SIMON : No sir, I don't have to, my Mom is a good cook.

TEACHER : Harold, what do you call a person who keeps on talking when people are no longer interested?
HAROLD : A teacher.
