I did BSL level 1 several years ago, which is the equivalent of how to get by on holiday in Deaf world, eg "Hi, what's your name?" and "where's the loo?". I started level 2, but you really have to be part of Deaf (with a capital D) culture to get anywhere - like learning any foreign language - and, despite crap hearing, I'm very much part of the hearing world. But anyway, I think this ad is great.
How ironic is it, then, that Pepsi's other ads during the American Superbowl didn't have subtitles? Bit of a mixed message there, methinks.
