In the long, long ago, I can remember a brand of Burger Rings knock offs called "Skips". They were shaped kind of like little shells, came in tiny packets, and their ads (with a little astronaut faget) were on TV constantly during Amazing and Aggro and that kind of shit.
Their only other notable feature was that they kind of melted in your mouth the way prawn crackers do.
But because of the generic name and its resemblance to a British brand of prawn snacks, I can't seem to find any trace of them ever existing.
Am I going a bit mad, m80-moos?.
