Curing My Friend's Fear Of Clowns

I want to go see the new “Joker” movie with my friend Austin Zajur (star of "Scary Stories To Tell In The Dark”), but he's too scared of clowns. My friend MarMar and I decided to prank Austin to help him get over his fear. We convinced him to spend 30 minutes alone with a Joker impersonator we found on Craigslist (it's actually me and I'm going to scare him).
