I had problems getting enough wood for the Ark, because there was a ban on cutting trees to protect the Spotted Owl. I finally convinced the U.S. Forest Service that I needed the wood to save the owls.
However, the Fish and Wildlife Service won't let me catch any owls. So, no owls.
The carpenters formed a union and went out on strike. I had to negotiate a settlement with the National Labor Union. Now I have 16 carpenters on the Ark, but still no owls.
When I started rounding up the other animals, I got sued by an animal rights group. They objected to me only taking two of each kind aboard.
