I worked construction for many years, here are some of the reasons we were sent home
Rain out
Snow out
Wind out
Mud out
Freeze out (working area iced over)
Sun out (too hot to work)
And now come the two great ones..........

Bug out (a swarm of bees took over the work area)

Drum roll...........
The winner is


Boat out ( While converting a tanker to a floating refinery a storm broke the mooring lines and the boat was blown across the harbour!!!!!)


Now top that if you can
