Just a quick video here I thought some of the American subscribers would find interesting, this is an actual advert getting aired in the UK.
There are also other similar ones featuring Top Cat and The Flinstones so I guess they have some sort of deal with Hanna-Barbera.
The voice actors I believe are Scott Innes (Alien Invaders, Cyber Chase) and Mindy Cohn (What’s New Scooby-Doo?) but not 100% sure.
