The giggles
I believe when you reach the giggle phase, that is the optimal dose, not that it would be easy to prescribe a certain amount to achieve it, but I think that THAT exact amount unlocks the "prankster" archetype without going into full "locked in the bathroom for an hour mirror-gazing, full introspection" mode. Others will surely disagree.
This is what I like about unlocking the giggle-mode prankster persona: Simultaneously, while everything looks plastic and oily with a rainbow luminescence and/or glowing and meaningful, you still can have the mental wherewithal to sarcasticaly marvel at how corny and fake everything looks like. It's simultaneously breathtakingly, overwhelmingly beautiful and comically cheesy and corny at the same time. It's just my opinion, though.
Nevermind, that probably didn't make sense.
