The rubber / eraser thing reminds me of when i worked in an ofiice in Australia. I'd been there a couple of days and the manager, a lady in her late 50's, walked out onto the sales floor and said ''can someone bring me some 'durex' quickly please''...
Durex - UK - the most popular brand of condom
Durex - Australia - selotape / scotch tape
I was almost walking towards her with my wallet out.
