A good one that I heard was the "Australianfor" angle grinder = "sparky wheel".
The photo and information came from the soldier himself but time does play tricks with memory and he had just fought a war. He probably had more important things to think about than trying to remember when exactly he drank a bottle of pop.
I did wonder if the beverage in question was in fact not Coca Cola but perhaps something else that has largely been forgotten in the UK, Dandelion & Burdock or maybe Ginger-beer.
