Someone’s just handed you a cookie with some smudged blue goo on it. You know your factory has three colours of icing, and you have a machine for each colour. You can look at any of the cookies and you know instantly which machine to fix. If you’d had multifunctional machines, each of which does the three colours, and you get a cookie every few hundred cookies with the ‘goo’ problem, it’s much more difficult to work out how to fix it.

Some people seem to have brains like the factory above.

I wish I was like that. I’ve got an All-in-One Cookie Maker MAX of a mind. Ingredients go in, and cooked and decorated cookies come out, but for years I’ve been trying to get it to make lasagne, and maybe if I just keep twiddling the knobs it might stop doing that funny sound and then I’ll finally get lunch.

Go on, have a cookie.
