Job interviews, should I mention my Asperger's?

Hi, I have a job interview next week, and I don't know whether to mention that I have Aspergers or not, would you? it's not something I like to mention but I feel I should mention it because I don't want any misunderstandings between myself and the staff,  as with my last job, which I recently got sacked from because of my  "erratic " behavior and " attitude". I never told them about my Asperger's when I started working there.
