Falling asleep in unusual places

Basic unusual places would consist of those such as:
In a bush.
Under a table.
The bathroom floor.
There are however extremely unusual places to go to sleep such as:
On top of the fridge.
In a cardboard box, in the middle of a stairwell.
On a traffic island.
Standing up, in a mosh pit, next to a stereo cab, at a rock gig.
Against all odds, it happens. To some more than others.
