It's always 1am before a work day when the brain goes into overdrive and you can't sleep.
I'd like a refund on this ride.
Oh good, you're up. Whilst you're there, could you catch me a morepork?
Isn't that always the case. 
more pork please. 
Yes but....have you seen Groundhog Day? 
Worked the last 18 months on an average of four and a half hours' sleep a night. Know the feeling..
