You're talkin' about something only Ronnie could do.
All this (minimal) talk about new ambassador has been shite, it's like Jesus dying and then someone saying "Oh for fuck's sake. Who's gonna be our new cult magician/saviour now? I vote Geraldus the sheep herder."
For starters Simon would never do it because he's not comfortable with "People speculating about death". Can't you notice that from his tweets? He's only comfortable pocketing gazillions from a show that makes fun of and trivializes death, poverty, incompetent parenting, etc.... and then giving it away to ensure the welfare of animals that like to rip off the faces of infants!
(And on a side-note here he hasn't even SEEN most of the episodes which do that because he stopped watching it in about 1991 or something after he left the show! See, he hasn't even seen one of the god-awful newest episodes from like 2011-present, (well actually they've pretty much all been at a whole new level of naff since they went widescreen in 2009) and he talks to US about pain! He hasn't even seen the Ted Nugent episode and he expects us to feel bad for him!)
