I have to agree with every single post in this thread! (Well, almost) and this commerical is fantastic.
Like Jolie_77, just said, it is similar to one of the famous joke, and finally, it has been displayed visually and I can see and agree with Jillio here, that the deaf community in the U.S within the Multimedia industry is going into exposure and every single deaf person in the states will love this commerical, and be proud of it. Congratulations to the company who decided to do this commerical in part of the deaf culture and all.
I'm happy to see that commerical and I would love to see one of the similarity around in Australia, fortunately. Perhaps in the furture, maybe?
But in the end, that is definitely a great commerical overall. Like the others, I believe that the hearing community would understand more with the visual commerical that relates to the deaf joke, well known in the whole deaf community, but not in the states. Well known deaf joke around the world.
WTG!
EDIT: I'm hihgly impressed.
