I have NEVER understood this 'speech impediment" excuse. Go back ten years - he never had it. yet, it's claimed he had it at a young age. He's got some sort of mental decline going on. Hey, it happens. It's nothing to be ashamed of. My mom is - well, us kids are dealing with it, and my dad is showing signs of it. It happens. Making excuses like "speech impediment" when watching him talk is just shameful.
