This is actually more of a plan for a long term kingship than one lasting just a day, but this is all I've got so live with it.

Bed as many women as possible (ordering any who resist to be put to death. But it's okay, it's not rape because I'll royally pardon myself!) to create a vast number of illegitimate heirs. Then wait a few years for them all to mature, fake my own death, and watch the fireworks.

We haven't had enough wars for the throne in England recently. I wanna see William and Harry go at it, although I wouldn't know which one to cheer for. Ponce or dope-smoking nazi? United or Chelsea? Republicans or Democrats? Murderers or rapists? Same principle.
