Damn, I almost spat chips all over my screen. Ah, that was truly ridiculous.
Come to think of it, maybe that's what all of this is really about. Every time Jake takes a shit, he curls out one of his parallel universe selves, and he can only get a new one when he finds another True Heir. So he has to keep digging them up in order to stay topped up. Recently, he probably got explosive diarrhoea from some bad Mexican food, which is why he's been going through so many True Heirs as of late.
