An open source program with a copy protection scheme where in order to launch you must refer to your copy of the GPL and answer questions about it.

"What is the fifth word of GPLv3, '3. Protecting Users' Legal Rights From Anti-Circumvention Law.'?

* 'Granted'
* 'Work'
* 'Circumvention'
* 'Deemed'"

RMS: "You should have received a copy of the GNU General Public License along with this program." [Moving closer] "Did you?" [Moving closer still] "Did you REALLY?"
