You try to break out.
You and your cellmate devise an elaborate plan to break out of jail. Being the artist you are, you sketch out a flore plan and exactly where you need to dig a tunnel to escape. You are so pleased with your work, you autograph it. Unfortunately, your cellmate delivers your artwork to the authorities in exchange for his freedom. What was going to be a 48 hour sentence in jail just turned into a 5 year sentence in the state penitentiary. Busted!
