Translator: Wrong!

I'm sitting at home watching the show Friends with my brother Heath and someone says Hola! and Heath says that he knows what they said, and is talking all big about how he know Spanish. So what do I do? I start throwing out random Spanish words and Heath thinking he is big stuff is trying to think of what I am saying, but he can't so he gets the computer and goes onto some Spanish to English translator and types in Como Estas? and it come up with, I don't even know what it was but it was definitely wrong, and he said that it was not so I had to get out my Spanish notes from Spanish 1 and prove him wrong.
