How did they do that rappng commercial

Easy how they did it. The promo was made in the mid to late 1990's, when both of the 2 Fat Ladies were still alive, and the show was being shown on The Food Network in the USA. Remember seeing the same promo,on The Food Network all those years ago. The Food Network and The Cooking Channel are owned by the same people/company. No surprise they still have that old footage after 10,12, or 15 years.
