The first person of the team comes on stage crying.
The next person comes out, asks the first one what’s the matter and the first one whispers in his ear. Then they both start crying, long and loud.
Several others come out on stage, one at a time and repeat the same action.
When everyone is on stage, crying, moaning, howling, sniffing and so on (using large handkerchiefs that were dipped in water before their entrance and wringing them out splashily) the last person comes out and asks aloud: “Why is everyone crying?”
They all answer in unison: “Because we haven’t got a skit!”
