(Have a man onstage with a blanket or something over his head)
Announcer: This is the ugliest man/woman in the world. To prove this, I have three volunteers who will each see for themselves the gruesomeness

Person 1 walks up, looks under the blanket, then fakes a death ( preferably falling with your face turned away) Someone comes up and drags them offstage

Person 2 does the same as person 1
and gets pulled offstage

Person 3 walks up, looks underneath the blanket, and then the person who is under the blanket screeches (softly)
and fakes a death

Person 3 looks at the announcer and then the announcer fakes a death

Person 3 walks off the stage
