I grew up in a predominantly Catholic neighborhood, and went to Catholic school. There was a family around the corner who had 3 boys that were mildy retarded. One day I asked my mother why they didn't go to the same school as me and my other friends. My mom said "because they're Jewish", without further explanation. So I made the association that "Jewish" meant "retarded", and it was years before someone cleared it up for me.
