Sometimes you need a license more esoteric than the WTFPL. This collection of strange software licenses should keep your project contributors preoccupied.
The Anyone But Stallman License arose from a strange conversation in

The Schrödinger License may now be safely linked to for discussion, but becomes exceptionally viral if used in a project.
The Bugs License takes the "feature, not a bug" motto and turns it into a core part of the software development experience.
