As much as I would love for Robin Williams to be back and brightening the world again it would be incredibly selfish of us to forget that he was incredibly unhappy in life and killed himself in a very unpleasant way because of it.
So definitely the centipede.
In Austin, there was a short period of time where all grocery stores were legally required to ditch plastic bags.
A successful campaign strategy for city council right after that was to run against the plastic bag ban because people kept forgetting their reusable bags. Everybody agreed they are bad but individualism and a sense of laziness prevailed. This is America.
