Need I describe this further? A piratical themed domination week would be awesome. Instead of the bumhole card you get the Broadside card; Shotgun is replaced by Pillage and Plunder, the list goes on.

You could increase the number of Lemon scoops given when speedruns are done (they look like doubloons), and the person who ends up with the most Lemon scoops at the end of the week gets a special E-Peen.
