Clowning Around

What if a very popular person convinced everyone in the world to try a bit of a special drink that was secretly a vat of acid, causing every person to have a permanent clown smile - think the Joker from Batman, Jack Nicholson version.

Scars cause skin to pull and stretch in phenomenally awkward ways, such as would be the case with a smile upon drinking a scaring, searing, acid drink that would immediately disturb the flow of facial gravity.

People would be unable to stop themselves from drinking for a few reasons: 1) the popular person would be very convincing, and likely would have a clown smile themselves, thus making the whole procedure either highly amusing or highly terrifying 2) the curiosity of the episode would make each single person want to find out if they themselves would be scared, or just maybe they are the one solitary human that is immune to the scaring properties of the acid.

This popular person would travel a lot; this would go without saying since I already said that this person made every single man, woman and child drink acid, so the acid drink would have to be in a protective container with a lid, it's probably in a sippy cup. That would further the ease of distributing the drink because sippy cups are usually associated with toddlers, hence one would assume the drink would be safe despite seeing the person prior being forever scarred, not to mention hearing the shrieks of their furious, laborious struggle with the acid. You'd think that vision only would make one want to desist from drinking, but no, you will go ahead and drink and thus permanently scar yourself with a clown smile, and all the while I will watch via my super high powered telescope thinking how you humans have settled your own demise.

I won't think in the begining that every single person will drink that drink, but low and behold, you will prove me wrong and every single one of you will.
