It’s Mother’s Day tomorrow – or perhaps Mothers’ Day – depending on your marital status – or indeed your understanding of the definition of the day. Perhaps you’ve forgotten to buy a present. Well, you’re out of time. Unless you buy something online – and perhaps, given that you’ve forgotten your mum, you should buy a clock. Here’s some fun ones from around the interwebs – and where to buy them. The good ones aren’t cheap.

Vaguely descriptive clock
