Three pastors from different faiths sponsor a gigantic revival meeting. After the revival ends, the three ministers get together to assess its effectiveness.
"The revival worked out great for us," one tells his colleagues. "We gained four new families."
"We did better than that," the second minister says. "We signed up six new families."
"Well," says the third, "we did even better than that. We got rid of our 10 biggest trouble-makers."
