Inversity is the tale of Bob and George, who are both brothers, Bob being slightly older. One day Bob realized that when anything bad happened to his brother George, something good happened to himself. For instance, if George falls and breaks his leg, perhaps Bob will win a free television from a contest.
Here is a tale...
One day Bob was bored and wanted something good to happen so he hired a homeless man to mug his brother. The homeless man did his job, and the very same day Bob met some random girl on the street and they went home and had sex.
