I like jokes about different trades and professions. Here is an old one about economists and their models that I came across the other day: An engineer, a physicist and an economist find themselves ship-wrecked on a desert island, with only a sealed can of baked beans to eat. How to open the can? The engineer proposes piercing the can with a sharp flint, whilst the physicist suggests leaving the can out in the mid-day the sun until it explodes. Meanwhile, the economist thinks for a long while and then says “Firstly, let’s assume that we have a can opener…”
Next time – one on engineers.
