Scream. Pound on the door. End up breaking it down.
Shout for help. If no one hears you, sit quietly. Someone will have to open the door eventually. Advoid looking at the clown.
Sit quietly and wait.
Scream and run quickly out of the theater! No one can get you to come back in.
Ask to leave. If they say no, you just close your eyes and be quiet.
Say no, no matter how much they beg.
Say no, but when they keep on begging, you go.
Quit! There is no way YOU would be a clown!
Are nervouse, but decide it's just acting and you can get through it.
Just do it.
