Clocks mess up my mind.
Some weeks ago, I was buying some oil, and the register said '$2.56'. And obviously my mind wasn't working normally because I didn't think 2^8 as I normally would.
Anyhoo, I handed her 3USD expecting 4 cents in return. It took me an hour to realise why she gave me 44 instead.
No. Wait. It was 2.54USD, 4 cents, and 46 cents. So my mind was working correctly. Except for the 'we're using base 60, right?' bit.
