you are right.

His act has several major points abouth us Chinese students:
1) We are more like to be nerves arround people
2)bad english
3)we are bad driver
4)at lost at times
The fact that his act makes us uncomfortable means he is right on. That is how people see us. If you were black, you won't feel that way.
Maybe a little bit overacted.. It is degrading a little bit.
