It came to me..in a lifetime of commercial watching,I don't think anything tops the blond or Dogs. Plain dogs,cartoon dogs,talking dogs selling everything. Blondes too. How many jet black haired Asian woman try to sell something that wasn't Asian in national ads? And,even she knows Dogs love bacon.
Every milf,soccer mom and trophy on TV are blonde. What gets me? even the nerdy blonds that you are supposed to laugh at (usually the mouse secretary) if you look close,and take off her horn rimmed glasses,and put up hair, is actually a young trim attractive woman. And she's blond.
Dogs,sell insurance, Gasoline, anything. A wide appeal- to you or the kids. McGruff- Lassie- Taco Bell Chihuahua. Tip of the iceberg.
The key to life? Get a blonde and a dog. He doesn't have to be blonde.
