As someone with a slight (I think/hope) lisp, couldn't they have gotten someone else to narrate? Might just be a personal opinion, but I know I'd rather have my friend/co-founder/professional voice actor talk rather than me in a commercial for my company rather than have everyone wondering throughout the ad: Does he have a lisp? Yeah he's got a lisp. Let me listen for the next 's' to confirm. Yep that's a lisp. Oh the commercial is done. What-dingo?
