I don't know if this has been brought up around here before (http://www.sitcomsonline.com/boards/showthread.php?t=328837) but I was watching an episode on Encore Black yesterday from the final season called "The Big Bribe" and I just couldn't help but notice the rather odd way in which Gary Coleman was speaking. It sounded like (as the title would suggest) had a strong lisp, as if it was hard for him to get his words out completely. I don't know if this was a byproduct of his other health issues or it was simply my imagination (in that he always talked like that).
