"I'm worried we might have exceeded our annual leave entitlement."
Here's another cartoon submitted for exhibition at this year's Shrewsbury Cartoon Festival, where the theme this year is "Time".
The cartoon was originally published in Prospect magazine in 2010 and I remember thinking at the time that it was a good example of how cartoons can be used as a spot of light relief amid a lot of text. Click here for details on commissioning cartoons.
This gag also features in my book of cartoons Penguin vs Polar Bear, which you you can buy at my shop page here.
