From one of the cartoons:
Now tells da folks how tasty them Oreo "double-stuffs" is.
This really rang a bell with me. Back in our performing days when we were doing our second US trip - this would be 1998 I think - quite ordinary seeming Americans kept sidling up to us and telling us that Oreo had just started selling "cookies" with double thickness filling. It was weird, like they were trying to get us to snort coke or (worse in their eyes, it seemed) drink beer. But no, it was just biscuits.
