Como se dice "moron" en Espanol?

I have no job. My cousins with the new Cuban restaurant have been looking for another bartender and server. I went to bartending school a few years ago. My cousins didn't know that. The positions were both filled about a week ago. I didn't know until two days ago they needed people because I've been looking at the clerical/admin ads in the paper, not restaurant ads. I'm going to have to kick my own ass now.
