Stop all the clocks
We’ve all been there – getting to bed late but worried about making it up in time for work in the morning. As long as you remember to set the alarm then you’ll be fine, sleepy, but there. It does help, though, if it’s the alarm that you remember to set.
This guy didn’t fare so well. How tired (or something else) he must have been to think that he was setting the alarm – all responsibly – when in fact he was doing a quick bit of math before bed?
