The Teflon reference reminded me. My wife was puzzled with idea that someone was referred to a Teflon Man - because things did not stick to him or he did not take responsibilty. It did not make sense to her.

It was only when she told me - that her puzzlement was made clear.

When the reference was made to Teflon - she thought of a substance here that was called 'Fablon'. Her confusion was that far from being non-stick - this was a material for lining cupboards and had an already sticky suface revealed when you pulled the backing off. This 'Fablon' was UK TV's Blue Peter's famous - sticky back plastic.
