Good one....Pakistani-American origin!

Inzamaam, a Pakistani child, entered his classroom on the first day of
school in Ohio (USA)

"What is your name?"  - asked the teacher.

"Inzamaam ". . .. - answered the kid.

"You are in America now.  From now on your name  will be Johnny,"
-replied the teacher.

In the evening, Inzamaam  returned home. "How was your day, Inzamaam?"
- asked his mother.

"My name is not Inzamaam. I'm in America and now my name is Johnny."

"Ah, are you ashamed of your name, are you trying to dishonor your
parents, your heritage, your religion? Shame on you!"
- and she beat him.

Then she called his father and he too beat him.

The next day Inzamaam returned to school..

When the teacher saw him with all the bruises she asked, "What happened
to you little Johnny"?

Well madam, 4 hours after I becoming an American,  I was attacked by
two Pakistanis At home."
