A blanket, people, and lots of personality! : )
A person stands with a blanket covering them. A counselor yells something like, “come see the ugliest person ever!” Every time people look under the blanket (without the audience seeing) they pretend to faint in disgust. When the last person looks under, the ugly person under the blanket pretends to faint.
(If you don’t get it, its because the person looking under the blanket is uglier than the person who is supposed to be.)
