The Vitiation of Vespasian
Imperator Caesar Vespasianus Augustus is well known for having said "An emperor ought to die standing" before he died, lying down. However, Ibi rectified this out of duty, by taking Vespasian down from behind and ripping off his head. It has been duly noted that by this point the series had descended into unnecessary killing and seemed to have lost all of its educational value. Slightly weaker now... "Oh.. Ibi. Again."
