"No speako Espanol" - SO OFFENSIVE TO RICHIE!
Either he was retarded and didn't learn spanish from his mother and brother (possibly father) and latino community they lived in or he is one of those latino americans who are like "I'm not mexican, so don't speak spanish to me" and makes the point of pretending to be completely oblivious to common knowledge spanish.
If you don't speak spanish, the first thing you learn is how to say "I don't speak spanish", and it is "no hablo" not "no speako".
His brother was fluent in Spanish. His mother was fluent. Both of them speak it throughout the movie.
I wish they had addressed this in the movie, either by explaining why he didn't speak it or explaining why he was pretending not to speak it.
