This one is a classic, and I'll steal it wholesale (including this post's title) from actualmalice.com:
In March 2003, Craig Veytia claims that Jason Mewes, "Jay" of "Clerks" and "Mallrats" fame, entered into an agreement assigning the rights to his life story to Veytia. Shortly thereafter, HBO announced that it was commissioning a documentary to be produced by Veytia's production company. The documentary titled "Rock Bottom," was to track Mewes' rehabilitation and efforts to kick his heroin habit.
Now, apparently Mewes is refusing to cooperate with the project and has disavowed the assignment agreement. Veytia, in turn, has filed a declaratory judgment action in Los Angeles Superior Court seeking a declaration that the assignment gives Veytia the right to "produce and exploit" Mewes' story.
