Stuff Happens started life at Britain's National Theatre with Alex Jennings as George Bush, directed by Nicholas Hytner.

The title is taken from a phrase used by Donald Rumsfeld when grilled by reporters about the widespread public violence that overtook Iraq following the American invasion in 2003. At the same press conference, he said "Freedom's untidy, and free people are free to make mistakes and commit crimes and do bad things."
