I was in a hotel room a few years ago and I woke up in the early hours and glanced at the digital clock radio. It displayed the time using six digits HH:MM:SS
Just at the moment I glanced it flicked over to 04:04:04. It occurred to me that, using calculator word logic, this would read ‘ho ho ho’ if viewed upside down. That year I produced a Christmas card with those digits on the front and ‘Christmastime’ printed upside down as the message on the inside. In the absence of any further explanation, absolutely nobody understood the card.
I've always liked that 56 = 7 x 8

I was looking at my digital clock last-night and it occurred to me that 4:56 is quite an interesting time.
