5、How you doing?pls reference friends when Joey said it...
When Joey says "how you doing" he's using slang of a proper greeting "how are you doing?". He's basically saying it in a funny way, and refrencing pop culture.
6、Even if your intelligence lower than others,if you find the correct method,you can improve your skills quickly/readily than others
