A man is on the top of a high-rise building. He looks like he
is
about to jump. Hundreds of people down the street are looking
up at him. Suddenly, he sees a policeman and a man in a white
coat inching their way close to him on the ledge.
"Don't try to convince me to step down. I've made up my
mind!"
The police shakes his head and says: "Relax, friend. The
doctor here just wants to know if you're willing to donate your
kidney after your death"
